Iridescence is also found in plants, animals and many other items. The range of colours of natural iridescent objects can be narrow, for example shifting between two or three colours as the viewing angle changes, Iridescence can also be created by diffraction. This is found in items like CDs, DVDs, some types of prisms, or cloud iridescence. In the case of diffraction, the entire rainbow of colours will typically be observed as the viewing angle changes.
|
|
Wing iridescence is another factor in H. cydno mating. Heliconius butterflies in general use thin-film iridescence and polarized light for mate recognition. H. cydno has blue iridescence which, at some angles, is 90% polarized. In experiments investigating polarized light as a signal in mating, it was found that when a female's wings were shown behind a depolarizing filter, she was approached at a significantly lower rate than when her wings were shown behind a non- depolarizing filter.

The margins of all fins are black, and the back has golden iridescence. Iridescence is particularly pronounced on the opercles (gill covers) which have a violet sheen on their posterior side. The iris is blue and also iridescent. Females and young are more yellow in color than the males.
|
|
Iridescence occurs due to visualised changes in coloration from the scattering of ultraviolet light. A male-only pattern of coloration due to this iridescence is seen exclusively under ultraviolet light, since females absorb light on the ultraviolet spectra. The presence of exclusively leucopterin in female wings explains the lack of iridescence in female common brimstones, since leucopterin absorbs only in the ultraviolet range. Therefore, the wings do not reflect and consequently do not scatter any ultraviolet light like male wings do.

|
Iridescence in soap bubbles Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, as well as certain minerals. It is often created by structural coloration (microstructures that interfere with light). Pearlescence is a related effect where some or all of the reflected light is white, where iridescent effects produce only other colours.

Iridescent mid altitude clouds Iridescent polar stratospheric cloud at sunset over Aberdeen, Scotland Cloud iridescence, seen above the sun covered with grey clouds, Pondicherry, India Cloud iridescence over County Kildare, Ireland Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface. It is a type of photometeor. This fairly common phenomenon is most often observed in altocumulus, cirrocumulus, lenticular,Answers.

Iridescence is the 'play' or 'fire' of rainbow-coloured light caused by very thin regular structures or layers beneath the surface of a gemstone. Similar to a thin film of oil on water, these layers interfere with the rays of reflected light, reinforcing some colours and cancelling others. Iridescence is seen at its best in precious opal.

Tiffany patented Favrile glass in 1892. Favrile glass often has a distinctive characteristic that is common in some glass from Classical antiquity: it possesses a superficial iridescence. This iridescence causes the surface to shimmer, but also causes a degree of opacity. This iridescent effect of the glass was obtained by mixing different colors of glass together while hot.

This "grazing iridescence" is brought about through diffraction of light (after back-reflection) by the wings' extremely steeply-set, multilayered rib-like scales (rather than the ridge-lamellae of most other iridescent butterflies, such as Morpho species). Such limited-view iridescence was previously only known from one other species, the riodinid Ancyluris meliboeus. In A. meliboeus, however, the iridescence is produced by ridge-lamellar scales and features a wider range of colours. The close evolutionary relationship between Troides and Ornithoptera butterflies is well demonstrated by the fact that commercial breeders have produced numerous hybrids between the two.

Many Pierre Shale ammonites, and indeed many ammonites throughout earth history, are found inside concretions. An iridescent ammonite from Madagascar Other fossils, such as many found in Madagascar and Alberta, Canada display iridescence. These iridescent ammonites are often of gem quality (ammolite) when polished. In no case would this iridescence have been visible during the animal's life; additional shell layers covered it.

It was long considered a subspecies of the square-tailed drongo (Dicrurus ludwigii) but a 2018 study of genetic divergences indicated that both were distinct species. It can be physically distinguished from D. ludwigii by the lack of white tips on the axillaries as well as having a dull purplish-blue iridescence rather than the greenish blue-black iridescence of D. ludwigii.

|
Initial studies showed that artificial replicas of the flower surface produced iridescence that bees could recognise. Later work suggested that the irregularities of the plant cells and surface resulted in the periodicity of the striations being too irregular to create clear iridescence and thus suggested that the iridescence is not visible to man and flower visiting insects. More recent papers have presented evidence that the flower is both visibly and measurably iridescent, and the striations have been shown to be sufficiently irregular to generate particularly strong scattering of light at short wavelengths, producing weak iridescence and a 'blue halo' (of which the halo is the dominant visible effect). It has also been demonstrated that the blue scattering increases the foraging efficiency of bumblebees in laboratory environments, although it remains unknown whether this effect translates to a meaningful advantage in the field.

These rod-shaped, narrow melanosomes were arranged in stacked layers, much like those of a modern starling, and indicated iridescence in the plumage of Microraptor. Though the researchers state that the true function of the iridescence is yet unknown, it has been suggested that the tiny dromaeosaur was using its glossy coat as a form of communication or sexual display, much as in modern iridescent birds.

PHOTOMETEORS, by Jesús Martínez-Frías If parts of clouds contain small water droplets or ice crystals of similar size, their cumulative effect is seen as colors. The cloud must be optically thin, so that most rays encounter only a single droplet. Iridescence is therefore mostly seen at cloud edges or in semi-transparent clouds, while newly forming clouds produce the brightest and most colorful iridescence. When the particles in a thin cloud are very similar in size over a large extent, the iridescence takes on the structured form of a corona, a bright circular disk around the Sun or Moon surrounded by one or more colored rings.

Paraparatrechina are small (typically around 1–2 mm in total length) formicine ants, which often reflect a metallic iridescence (blue, purple and pink hues have been observed) under light microscopy. In darker species, the iridescence tends to be a darker bluish- purple, while lighter colored species either show little iridescence or reflect a more pinkish-purple hue. Paraparatrechina are usually easily distinguishable from other formicine genera by a unique mesosomal setal pattern: two pairs of erect setae on the pronotum, one pair on the mesonotum and one pair on the propodeum. Nylanderia, the genus most likely confused with Paraparatrechina, never possesses a pair of erect setae on the propodeum.

Under certain conditions, window film will exhibit iridescence also known as thin film Interference (TFI) and is well known in the aviation industry. TFI essentially refers to colours gradually changing as the angle of view or the angle of illumination changes. This phenomenon usually occurs at night, when the source of illumination within a building is fluorescent lighting. The amount of iridescence may vary from almost imperceptible to very visible.
|
|
The blue iridescence is produced by thin-film interference produced by a thin layer of cells with lamellar structure in the upper cuticle of leaves. It is suggested that this adaptation reduces the effect of strong sun beams filtering through the canopy that would otherwise damage shade-adapted species. Blue iridescence is found also Selaginella uncinata and both species are adapted for extreme shade below the forest canopy.

Roof of Matthias Church, Budapest Many Zsolnay ceramics are noted for the use of the eosin process that was introduced in 1893. The process results in a light red iridescence of the first prepared hue, hence the term eosin (Greek eos, flush of dawn). Different eosin colours and processes were developed over time. The eosin-based iridescence became a favourite of art nouveau and Jugendstil artists, among them Sándor Apáti Abt, Lajos Mack, Géza Nikelszky, and József Rippl-Rónai.

Intermediate grades have ranges of 240–180°. ; Brightness of colors (iridescence) : The brightness of colors and their iridescence is essentially dependent on how well-preserved the nacreous shell is, and how fine and orderly the layers of aragonite are. The quality of the polish is also a factor. The "dragon skin" cracking usually hinders its value; the most prized ammolite is the sheet type (see formation) that has broad, uninterrupted swathes of color similar to the "broad flash" category of opal.
|

Like other woodlice, T. pusillus eats decaying plant matter of various kinds, although only alder litter is capable of sustaining a stable reproducing population. Predators of T. pusillus include the common shrew Sorex araneus, lycosid and dysderid spiders, centipedes such as Lithobius variegatus and perhaps carabid beetles. Trichoniscus pusillus is susceptible to infection by isopod iridescence virus, or Iridovirus (Iridoviridae). This is first apparent as a blue sheen on the unpigmented underside of the animals, but soon spreads to give the entire exoskeleton a bluish iridescence.

NMEs El Hunt wrote, "Far from making vague allusions to the events prior to Iridescence, Brockhampton lay them bare, atop some of their most adventurous work to date." The Line of Best Fit critic Sam Higgins stated that "the more you listen, the more intricacies you notice. The more you listen, the more you realise just how defining this record will be for the future of Brockhampton.

Circumhorizontal arcs, especially when only fragments can be seen, are sometimes confused with cloud iridescence. This phenomenon also causes clouds to appear multi-coloured, but it originates from diffraction (typically by liquid water droplets or ice crystals) rather than refraction. The two phenomena can be distinguished by several features. Firstly, a circumhorizon arc always has a fixed location in the sky in relation to the Sun or Moon (namely below it at an angle of 46°), while iridescence can occur in different positions (often directly around the Sun or Moon).

In Micrographia, Hooke postulated that the iridescence in peacock feathers was caused by thin, alternating layers of plate and air. In 1704, Isaac Newton stated in his book, Opticks, that the iridescence in a peacock feather was due to the fact that the transparent layers in the feather were so thin.Structural colors in the realm of nature By Shūichi Kinoshita – World Scientific Publishing 2008 pages 3–6 In 1801, Thomas Young provided the first explanation of constructive and destructive interference. Young's contribution went largely unnoticed until the work of Augustin Fresnel.

Colors resulting from different feather pigments Left: turacin (red) and turacoverdin (green, with some structural blue iridescence at lower end) on the wing of Tauraco bannermani Right: carotenoids (red) and melanins (dark) on belly/wings of Ramphocelus bresilius The colors of feathers are produced by pigments, by microscopic structures that can refract, reflect, or scatter selected wavelengths of light, or by a combination of both. Most feather pigments are melanins (brown and beige pheomelanins, black and grey eumelanins) and carotenoids (red, yellow, orange); other pigments occur only in certain taxa – the yellow to red psittacofulvins (found in some parrots) and the red turacin and green turacoverdin (porphyrin pigments found only in turacos). Structural coloration is involved in the production of blue colors, iridescence, most ultraviolet reflectance and in the enhancement of pigmentary colors. Structural iridescence has been reported in fossil feathers dating back 40 million years.

In addition to simple body colour, minerals can have various other distinctive optical properties, such as play of colours, asterism, chatoyancy, iridescence, tarnish, and pleochroism. Several of these properties involve variability in colour. Play of colour, such as in opal, results in the sample reflecting different colours as it is turned, while pleochroism describes the change in colour as light passes through a mineral in a different orientation. Iridescence is a variety of the play of colours where light scatters off a coating on the surface of crystal, cleavage planes, or off layers having minor gradations in chemistry.

Iridescence is an optical phenomenon of surfaces in which hue changes with the angle of observation and the angle of illumination. It is often caused by multiple reflections from two or more semi-transparent surfaces in which phase shift and interference of the reflections modulates the incidental light (by amplifying or attenuating some frequencies more than others). The thickness of the layers of the material determines the interference pattern. Iridescence can for example be due to thin-film interference, the functional analogue of selective wavelength attenuation as seen with the Fabry–Pérot interferometer, and can be seen in oil films on water and soap bubbles.

|
This takes several seconds or minutes, and the mechanism is not understood. However, iridescence can also be altered by expanding and retracting the chromatophores above the iridophores. Because chromatophores are under direct neural control from the brain, this effect can be immediate. Cephalopod iridophores polarize light.

Iridescence is the phenomenon when light interacts with a particular surface, and at differing angles of illumination and observation the color begins to gradually change. The Morpho Menelaus' characteristic iridescent wings has a unique wing structure. The ground scales are covered by a set of longitudinal ridges, and within the ridges are layers of lamella. Because the size of the microstructure is the same as the wavelength of light, the layers in the wings react strongly with visible light. The ground and cover scales have an observable “Christmas-tree” structure which is responsible for the diffraction or bending of light pattern of the wings which results in the characteristic iridescence blue color.
|
|
In biology, this type of iridescence results from the formation of diffraction gratings on the surface, such as the long rows of cells in striated muscle, or the specialized abdominal scales of peacock spider Maratus robinsoni and M. chrysomelas. Some types of flower petals can also generate a diffraction grating, but the iridescence is not visible to humans and flower-visiting insects as the diffraction signal is masked by the coloration due to plant pigments. In biological (and biomimetic) uses, colours produced other than with pigments or dyes are called structural coloration. Microstructures, often multilayered, are used to produce bright but sometimes non-iridescent colours: quite elaborate arrangements are needed to avoid reflecting different colours in different directions.

In 1816, Fresnel helped to establish the wave theory of light.Thin-film optical filters By Hugh Angus Macleod – Institute of Physics Publishing 2001 Pages 1–4 However, very little explanation could be made of the iridescence until the 1870s, when James Maxwell and Heinrich Hertz helped to explain the electromagnetic nature of light. After the invention of the Fabry–Perot interferometer, in 1899, the mechanisms of thin-film interference could be demonstrated on a larger scale. In much of the early work, scientists tried to explain iridescence, in animals like peacocks and scarab beetles, as some form of surface color, such as a dye or pigment that might alter the light when reflected from different angles.
|
|
He also found that bleaching the pigments from the feathers did not remove the iridescence. This helped to dispel the surface color theory and reinforce the structural color theory.Structural colors in the realm of nature By Shūichi Kinoshita - World Scientific Publishing 2008 Page 165-167 In 1925, Ernest Merritt, in his paper A Spectrophotometric Study of Certain Cases of Structural Color, first described the process of thin-film interference as an explanation for the iridescence. The first examination of iridescent feathers by an electron microscope occurred in 1939, revealing complex thin-film structures, while an examination of the morpho butterfly, in 1942, revealed an extremely tiny array of thin-film structures on the nanometer scale.

Tube blush was also extremely popular. Lipstick in the 1970s tended to be either color or gloss; popular hues included deep pink, purple, and raspberry. Improvements in chemistry enabled the introduction of waterproof mascara along with better lash lengtheners and thickeners. Matte colors were popular for eyes, in contrast to the iridescence that characterized 1960s make-up.
|
|
The ground color consists of a fine zigzagged mottling of whitish and light brown, through which the underlying nacre shines with a golden iridescence. There are several narrow spiral lines articulated remotely with white dots. And on the latter part of the whorl these are replaced by bands or lines of crimson. The aperture is oblong.

Dictyotaceae is large family of brown algae (class Phaeophyceae). Members of this order generally prefer warmer waters than other brown algae. One genus in this order is calcareous, Padina, the only calcareous member of this class. Lobophora variegata (= Pocockiella varieagata) often presents a beautiful blue iridescence due to microscopic bacteria which live on the surface of the blades.

A bubble is made of transparent water enclosing transparent air. However the soap film is as thin as the visible light wavelength, resulting in interferences. This creates iridescence which, together with the bubble's spherical shape and fragility, contributes to its magical effect on children and adults alike. Each colour is the result of varying thicknesses of soap bubble film.
|
|
Pearlescence is an effect related to iridescence and has a similar cause. Structures within a surface cause light to be reflected back, but in the case of pearlescence some or all of the light is white. Artificial pigments and paints showing an iridescent effect are often described as pearlescent, for example when used for car paints.

The interstices are under the lens finely striated, the striae running parallel to the ridges. These fine striae cause interference with the light, giving rise to iridescence when viewed obliquely. The aperture is circular and continuous. The lip is broadly margined, the margin being sculptured in a manner similar to the other portion of the body whorl.

The female is 8.4–9 cm long and weighs 3.5 g. She is bright green above and duller green below, with a grey throat and breast. Her tail is rounded, mainly green near the body but with a blue-black lower half and white corners. Young males lack any violet or iridescence and are bronze-coloured below.
|
|
The upper surface of the female abdomen ranges from yellow to red or even white or black and is marked with black sigilla. The ventral surface of the abdomen bears yellow or orange marks, and the median spines can show a bluish iridescence. The male of the species measures only 1.5 mm, with stout, conical spines.

Normally, a single laser beam is used in interferometry, though interference has been observed using two independent lasers whose frequencies were sufficiently matched to satisfy the phase requirements. This has also been observed for widefield interference between two incoherent laser sources. White light interference in a soap bubble. The iridescence is due to thin-film interference.

The forewings are irregularly and almost equally marked with iridescent gold and purplish fuscous. The markings are typically in the form of transverse bands across the wing but are sometimes fragmented into large irregular spots. The hindwings are usually slightly darker and less lustrous than the forewings though usually with a slight purplish iridescence near the apex. The scales are relatively broad.
|
|
Through chemical extraction and analysis, two possible pigments have been identified that may contribute to the common brimstone's wing coloration. Xanthopterin is responsible for the sulphur yellow colour of the male wings since it absorbs in the violet range. Leucopterin was extracted from the white wings of females. The difference in wing pigmentation contributes to the distinct iridescence patterns of males and females.

The true K. bicirrhis is easily separated from K. vitreolus. K. bicirrhis reaches a significantly larger size, up to standard length, and most of its body is not clearly transparent (only obviously transparent around the head). The body of K. bicirrhis is mostly opaque and light greyish. When struck by light, it has an iridescence, and it turns milky white when it dies.
|
|
The dorsal scales a layer of dark (indigo-brown) pigmentation just below the surface on each scale that enhances the iridescence. The ventral scales are greyish-white. This species differs from its sister taxon Xenopeltis unicolor in several ways. It has a singular postocular scale rather than two, fewer ventral, supralabial, and infralabial scales, a shorter tail, and fewer maxillary teeth.

Eduard Prochaska, with the company since 1880, served as director. The sons and grandsons of the workers employed in Joh. Lötz's glassworks were the tribe of the factory staff, a testament to the good understanding between the employer and the worker. Similar to the glasses from Louis Comfort Tiffany, Loetz was able to produce colored glasses with high level of metallic iridescence.

The Krabi mouth-brooding betta is an oblong fish with rounded fins, growing to a length of about . The basic colour is yellowish-brown or greyish-brown with three faint longitudinal stripes. The gill-cover has a bluish-green patch and the fins have a blue iridescence. The pelvic fins are short and the anal fin long, with a dark margin.
|
|
The deep color of its belly may mask the animal's bioluminescence to hide it from potential predators. Its "combs," rows of cilia on its body, have a sparkling iridescence. Specimens examined have ranged between 1.5 and 16 centimeters in length and 1.2 to 10 centimeters in width. Comb jellies do not sting and recent studies have shown that they are not actually cnidarians.

The shell is yellowish or greenish brown with green rays. The nacre of the shell is purplish or greenish with some iridescence. This mussel is native to the ACF River Basin, the watershed of the Apalachicola, Chattahoochee and Flint Rivers around the intersection of the states of Alabama, Georgia, and Florida. Its range has declined 80% from the known previous distribution.
|
|
The tail and primary flight feathers and primary coverts are black, while the secondary flight feathers are white. The secondary coverts are a dark iridescent green. This iridescence is lost outside of the breeding season and the plumage is duller. It exhibits sexual dimorphism, the female has a barred rather than green neck and otherwise resembles the non-breeding male.

The green honeycreeper is 13–14 cm (5-5.5 in) long and weighs 14 to 23 grams, averaging about 19 grams. It has a long decurved bill. The male is mainly blue-tinged green with a black head and a mostly bright yellow bill. The female green honeycreeper is grass-green, paler on the throat, and lacks the male's iridescence and black head.

Nuummite is usually black in colour and opaque. It consists of two amphiboles, gedrite and anthophyllite, which form exsolution lamellae that give the rock its typical iridescence. Other common minerals in the rock are pyrite, pyrrhotite and chalcopyrite, which form shimmering yellow bands in polished specimens. In Greenland the rock was formed by two consecutive metamorphic overprints of an originally igneous rock.

Tasmantrix tasmaniensis is a moth of the family Micropterigidae. It is known from in wet forests of western Tasmania.Micropterigidae (Lepidoptera) of the Southwestern Pacific: a revision with the establishment of five new genera from Australia, New Caledonia and New Zealand The forewing length is 3.7 mm for males. The forewing ground colour is rich brown with strong coppery-bronze iridescence.

The iridescence of lumachella is fragmentary and not nearly as brilliant as that of ammolite. Despite these differences, lumachella may be considered synonymous with ammolite in some circles. The predominantly blue-green iridescent shell of abalone (or paua; genus Haliotis) is one last possible imitation. Abalone shell is inexpensive and plentiful owing to the commercial mariculture of these gastropods for their meat.

This is Mythos' debut on the Higher Octave label, consisting mostly of previously released material. The liner notes claim this release includes "the best of the previously released album Introspection plus seven new tracks," but a number of the remaining songs were included on Iridescence. Only "The Odyssey" do not appear to have been released prior to this eponymous album.

Chloriridovirus is a genus of viruses, in the family Iridoviridae. Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as natural hosts. There are currently five species in this genus including the type species Invertebrate iridescent virus 3. Diseases associated with this genus include: yellow-green iridescence beneath the epidermis (early mosquito larval stages are most susceptible to infection).

All fins are spineless and lightly pigmented in shades of brown. Sabertooth fish are usually a drab, light to dark brown when preserved; however, a brassy green iridescence is seen on the flanks, cheeks, and ocular region of well- preserved specimens. The naked skin is easily torn. The Atlantic sabertooth (Coccorella atlantica) is the largest species, at up to 18.5 cm standard length.

Secondly, the colour bands in a circumhorizon arc always run horizontally with the red on top, while in iridescence they are much more random in sequence and shape, which roughly follows the contours of the cloud that causes it. Finally, the colours of a circumhorizon arc are pure and spectral (more so than in a rainbow), while the colours in cloud iridescence have a more washed-out, "mother of pearl" appearance. Confusion with other members of the halo family, such as sun dogs or the circumzenithal arc, may also arise, but these are easily dismissed by their entirely different positions in relation to the Sun or Moon. More difficult is the distinction between the circumhorizontal arc and the infralateral arc, both of which almost entirely overlap when the Sun or Moon is at a high elevation.

The bar- tailed trogon averages about 28 cm (11 inches) long. The bill and feet are yellow, and the tail, long and broad as usual for trogons, has the underside narrowly barred with black and white. The male's head is blue-black with bronze iridescence. Below the eye are two yellow or orange patches of bare skin; above the eye is a yellow or grey patch.
|

This species can reach a length of SL. The dorsal fin has seven to nine soft rays, the pectoral fin eleven to fourteen and the anal fin twenty-seven to thirty-two. There are thirty-two to thirty-four scales along the lateral line. Coloring is very vivid, especially in the males. They are a tan/brown, with green and blue iridescence, more noticeable in the males.
|
|
If it were pigmental, these changes would not cause differences in iridescence. The structural coloration of the male dorsal wings is affected by environmental factors. There is an increase in ultraviolet coloration coverage with increasing temperature, increasing precipitation, and decreasing latitude. This has been possibly attributed to several factors, such as the greater abundance and quality of resources in areas with these environmental conditions.

The Laysan duck is teal-sized and dark brown, with a prominent white eye-ring. The bill is short and spatulate, dark green with variable black blotching in males, and dull orange with variable black blotching in females. The Laysan duck usually has a ring of fat around its neck. Some males show faint iridescence on the head or neck and have slightly upturned central tail feathers.

Pastel refers to colors with high brightness and low saturation. Some phenomena are due to related optical effects, but may or may not be described separately from the color name. These include gloss (high- gloss shades are sometimes described as 'metallic'; this is also a distinguishing feature of gold and silver), iridescence or goniochromism (angle-dependent color), dichroism (two-color surfaces), and opacity (solid vs. translucent).

Dives is a genus of Neotropical birds in the family Icteridae. The melodious blackbird lives in Mexico and Central America; the scrub blackbird in Ecuador and Peru. The three species look similar, with plumage ranging from brownish black in juveniles to black with iridescence (green, blue, or violet) in adults, slightly more iridescent in males. The bare parts are black and the eyes are dark brown.
|
|
This species counts with 25 to 30 anal soft rays. Its dorsum is a dull grey colour with a pale green iridescence. Its maxillary band of teeth forms a continuous row, and its snout protrudes with upper jaw tooth bands which are somewhat exposed when the animal's mouth is closed; it possesses a large median vomerine tooth plate. The fish habitates large rivers and enters flooded forests.
|
|
Its color is usually yellow, brown, or gray to gray-black, and it may be shiny or dull. Its luster is adamantine, resinous to submetallic for high iron varieties. It has a yellow or light brown streak, a Mohs hardness of 3.5–4, and a specific gravity of 3.9–4.1. Some specimens have a red iridescence within the gray-black crystals; these are called "ruby sphalerite".
|
|
The red iridescence is highly directional and appears dull black from many angles. The female has a notched tail with outer feathers banded in green, black, and white and a white throat that may be plain or lightly marked with dusky streaks or stipples. Males are smaller than females and have slightly shorter bills. Juvenile males resemble adult females, though usually with heavier throat markings.

|
The pinfish is a small fish, growing only to about . Both the male and the female have a silvery sheen with five to six vertical bars on the side. They have olive backs with yellow and white pigmentation and blue, green, and purple iridescence. The anterior dorsal fin has 12 rigid, spiny rays capable of superficially puncturing human skin, giving the species its common name, pinfish.

One of the females was observed to oviposit at about 7:30 pm PDT. She laid a total of 40 eggs in the sand. The eggs were about 1.5 x 3 millimeters (less than 0.1 square inch), almost kidney-shaped, and pure white with a slight pink iridescence. Female flower-loving flies possess specialized egg-laying organs on the last segment on their abdomens (acanthophontes).

The hermits are tropical and subtropical hummingbirds in the subfamily Phaethornithinae, comprising 30–40 species in six genera. They occur from southern Mexico, through Central America, to South America as far south as northern Argentina. Their plumage typically involves greens, browns, rufous or grey. Most species show some green or bronze iridescence to the upperparts, but this is far less conspicuous than that of many other hummingbirds.

The bloater is a small, silvery-coloured whitefish with a pink and purple iridescence. It has a greenish tinge above, and a whitish belly. It is very similar to the kiyi, from which it may be distinguished by its lighter upper lip and smaller eye. Its body is deepest at its middle, it has small and pale fins, and it has 40–47 long gill rakers.
|
|
Coloration is olive on the back, fading to silver with a rosy iridescence on the sides, fading to white on the belly. Fish under show yellowish-brown spots on the flanks, somewhat smaller than the spots of the Atlantic Spanish mackerel, Scomberomorus maculatus. Its cutting-edged teeth are large, uniform, closely spaced and flattened from side to side. These teeth look very similar to those of the bluefish, Pomatomus saltatrix.

It was common in some of the ancient cultures of Asia to attach beetlewing pieces as an adornment to paintings, textiles and jewelry. Different species of metallic wood-boring beetle wings were used depending on the region, but traditionally the most valued were those from beetles belonging to genus Sternocera. Their wings were valued for their beautiful and hardy metallic emerald iridescence. The shiny appearance of beetlewings is long-lasting.
|
|
The eye is dark brown and the beak and legs are black. The juvenile male is similar to the adult male but the upper parts lack the iridescence and are a dusky greyish-olive, while the underparts are dusky yellowish-olive. The juvenile female resembles the adult female but is generally duller and lacks the metallic fringes to the feathers of crown and mantle. The underparts are a dull yellowish-green.

Agate Agate is a variety of chalcedony characterized by either transparency or color patterns, such as multi-colored curved or angular banding. Opaque varieties are sometimes referred to as jasper. Fire agate shows iridescent phenomena on a brown background; iris agate shows exceptional iridescence when light (especially pinpointed light) is shone through the stone. Landscape agate is chalcedony with a number of different mineral impurities making the stone resemble landscapes.
|
|
Both sexes look very dark unless the sun catches the iridescence of the plumage and the brilliant colours flash in the sunlight. The adult male is green-bronze dorsally, becoming more bronzed on the black-tipped tail. The crown is violet, the throat gorget bright blue-green, and the rest of the head black apart from a white spot behind the eye. The chest is green-bronze and the belly grayish.

Compared to the Eurasian magpie, it is somewhat stockier, with a proportionally shorter tail and longer wings. The back, tail, and particularly the remiges show strong purplish-blue iridescence with few if any green hues. They are the largest magpies. They have a rump plumage that is mostly black, with but a few and often hidden traces of the white band which connects the white shoulder patches in their relatives.
|
|
Also, a number of other species exist which are tawny orange or dark brown (for instance M. hecuba and M. telemachus). Some species are white, principal among these being M. catenarius and M. laertes. An unusual species, fundamentally white in coloration, but which exhibits a stunning pearlescent purple and teal iridescence when viewed at certain angles, is the rare M. sulkowskyi. Some Andean species are small and delicate (M. lympharis).

The body of Facelina bostoniensis is translucent white with a pink coloured hue around the mouth. The oesophagus, situated just behind the rhinophores, is clearly visible as a curved red tube. There are some patches of white pigment on the head, between the rhinophores and down the tail of the animal. Some individuals have blue iridescence in small areas around the head and rarely specimens with extensive blue colouration are found.
|
|
It also differs from Calamus pennatula in that it has more pectoral rays. Jolthead porgies have a blue line under each eye, and their mouths are rimmed in orange. The fish's overall color is a brassy silver with occasional blue/green iridescence, making it one of the dullest-colored member of its genus. The largest recorded Jolthead porgy was 76 cm, while they commonly grow up to 54 cm.

Electrochromic paints can be applied to plastic substrates as well, using a different coating chemistry. The technology involves using special dyes that change conformation when an electric current is applied across the film itself. This new technology has been used to achieve glare protection at the touch of a button in passenger airplane windows. Color can also change depending on viewing angle, using iridescence, for example, in ChromaFlair.
|
|
The word iridescence is derived in part from the Greek word ἶρις îris (gen. ἴριδος íridos), meaning rainbow, and is combined with the Latin suffix -escent, meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of the gods. Goniochromism is derived from the Greek words gonia, meaning "angle", and chroma, meaning "colour".
|
|
The upper parts are a dark golden-brown tinged with a slight iridescence and the underparts are a lighter brown with a golden sheen. It has a compact, streamlined body and a wedge- shaped head and pointed muzzle. It has muscular shoulders, short powerful forelimbs and strong digging claws. The third claw is enlarged and there is no fifth digit and only a vestigial first and fourth digit.

Press, New Haven, CT. The head and neck of the adult are bare, and the scaly skin is a dark grey. The black downward- curved bill is long and very wide at the base. The plumage is mostly white, with the , , and tail being black and having a greenish and purplish iridescence. The legs and feet are dark, and the flesh-coloured toes are pink during the breeding season.
|
|
The colors can be restored by moistening the surfaces with water. Iridescence (or goniochromism) in jewel bugs like Poecilocoris lewisi are the result of structural coloration. Instead of pigments, the colors are caused by the interference, diffraction, or scattering of light by numerous tiny structures. In Poecilocoris lewisi, multiple tiny conical protuberances around 900 nm in height and averaging at a diameter of 360 nm are scattered on the epicuticle.
|
|
These structures affect light passing through them, producing their oily- looking blue sheen (known as the Tyndall effect or Mie scattering). In other species like the African shield bug (Calidea panaethiopica), the dorsal cuticle is dotted with tiny regularly spaced hemispherical cavities. The depressions act like Bragg mirrors. When light hits the pitted surface, it gives off multiple reflections resulting in the distinctive two tone yellow- blue iridescence.
|
|
Their plumage typically involves greens, browns, rufous or grey. Most species show some green or bronze iridescence to the upperparts, but this is far less conspicuous than that of many other hummingbirds. The male and female plumages of hermits are very similar, with differences limited to details of bill- shape, tail-shape and/or strength of colours/patterns. No species of hermit show the strong sexual dimorphism usually associated with hummingbirds.

The Giganturidae are slender, slightly tapered fish with large heads dominated by large, forward-pointing, telescoping eyes with large lenses. Their heads end in short, pointed snouts. The highly extensile mouth is lined with sharp, slightly recurved and depressible teeth and it extends well past the eyes. The body lacks scales, but is covered in easily abraded, silvery guanine, which imparts a greenish to purplish iridescence in life.
|
|
The iridescence signal of flowers is thus only appreciable very locally and hence not visible to man and flower visiting insects. However, natural gratings do occur in some invertebrate animals, like the peacock spiders, the antennae of seed shrimp, and have even been discovered in Burgess Shale fossils. Diffraction grating effects are sometimes seen in meteorology. Diffraction coronas are colorful rings surrounding a source of light, such as the sun.
|
|
Diffraction can create "rainbow" colors when illuminated by a wide-spectrum (e.g., continuous) light source. The sparkling effects from the closely spaced narrow tracks on optical storage disks such as CDs or DVDs are an example. Similar rainbow effects seen in thin layers of oil (or gasoline, etc.) on water are not caused by a grating but rather by iridescence in reflections from the closely spaced transmissive layers.
|
|
Some species also possess iridophores or leucophores, which do not contain true pigments, but light-reflective structures that give iridescence. An extremely uncommon type of chromatophore, the cyanophore, produces a very vivid blue pigment. Amelanism in fishes, amphibians, reptiles and birds has the same genetic etiology as in mammals: loss of tyrosinase function. However, due to the presence of other pigments, other amelanistic vertebrates are seldom white and red-eyed like amelanistic mammals.
|
|
The gametophytes (see below) often show a blue iridescence at the tip of the fronds and fertile sporophytes show a spotty pattern. Mastocarpus stellatus (Stackhouse) Guiry is a similar species which can be readily distinguished by its strongly channelled and often somewhat twisted thalli. The cystocarpic plants of Mastocarpus show reproductive papillae quite distinctively different from Chondrus. When washed and sun-dried for preservation, it has a yellowish, translucent, horn-like aspect and consistency.

The scales of a snake primarily serve to reduce friction as it moves, since friction is the major source of energy loss in snake locomotion. Rainbow boas get their name from the coloration of their scales caused by iridescence. The ventral (or belly) scales, which are large and oblong, are especially low-friction, and some arboreal species can use the edges to grip branches. Snake skin and scales help retain moisture in the animal's body.

The adult male Carib grackle is long with a long wedge-shaped tail, although the latter is not so long as other grackles. Its plumage is entirely black with a violet iridescence, its eyes are yellow, and it has a strong dark bill. The adult female is long, with a shorter tail and brown plumage, darker on the upperparts. Young males are shorter tailed than adult males and have some brown in the plumage.

Shape is generally cylindrical or elongate to ovoid, with lengths ranging from , although most species are under . Catoxantha, Chrysaspis, Euchroma and Megaloxantha contain the largest species. A variety of bright colors are known, often in complicated patterns. The iridescence common to these beetles is not due to pigments in the exoskeleton, but instead is caused by structural coloration, in which microscopic texture in their cuticle selectively reflects specific frequencies of light in particular directions.

Astrapia is derived from the Greek 'astrapios' or 'astrapaios', meaning lightning or a flash of lightning, possibly a reference to the iridescence of the plumage. The genus is suggested to be monophyletic, roughly six million years old, and forms a sister-group with the two species in the genus Paradigalla. Astrapia and Paradigalla are members of a larger clade that includes the other long-tail birds-of-paradise from the genus Epimachus.

When dancing, they wiggle their dorsal, anal, and caudal fins to show off their bright blue iridescence. Then, suddenly, they do a full stop, holding completely still for a few seconds with no visible motion. After the pause, they continue dancing again, often moving up and down in their eagerness to woo the female into their respective clumps of dense plants. Females swim in and out of the males' territories to spawn.

Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. In some species, pigments accrue over very long periods during an individual's lifespan. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures.

Teinopalpus imperialis, the Kaiser-i-Hind, is a rare species of swallowtail butterfly found from Nepal and north India east to north Vietnam. The common name literally means "emperor of India". The Kaiser-i-Hind is much sought after by butterfly collectors for its beauty and rarity. The green iridescence of the wings has been found to be due to three-dimensional photonic structure of the scales and is the subject of much research.

The rufous-vented ground cuckoo is a large ground-dwelling bird with sturdy legs and a long tail. It has a brown head, greenish-brown crest and curved beak. The upper parts and tail are dark with a greenish, bluish or purplish iridescence, and the underparts are whitish to pale tan. The subspecies vary primarily in the details of the chest—and crown—pattern, and the colour of the tail and wings.

It is slender-bodied and silvery with pinkish iridescence on its sides. Diet is predominantly zooplankton and insect larvae, although fish eggs and larvae, including those of their own species are also documented. Small fish, including some minnow species, are also known to be consumed at times. Northern cisco are preyed upon by a wide variety of predatory species, and have a particularly important place in the diet of lake trout (Salvelinus namaycush).

Obi paradise-crows are blackish overall, with a bluish-green sheen/iridescence to the feathers. The flight feathers are a light brownish, and the tail feathers have a pronounced bluish sheen to them. They have a crow-like head and bill; the bill is a cool light gray. Also, they have distinctive and beautiful, scarlet-red eyes and blackish to grayish legs and feet with sharp claws adapted for their perching lifestyles.
|
|
They have a layer of dark pigmentation just below the surface on each scale that enhances the iridescence. The youngs look very similar to the adults, except that they have a strong white "collar" of scales evident just below the head. This coloration fades within the first year. This is a primitive form of snake with both boid and python characteristics; which family it belongs to is still a matter of debate.

Allochares azureus is a distinctive species of spider wasp, especially in the shape of the head which is convex in the front and concave in its rear, this is especially marked in the males. It also has a characteristic excavated propodeum which has conical teeth pointing towards the wasp's posterior. The females lack a tarsal comb. The body of the wasp is black but the short hairs cause it to have blue or green iridescence.

For two months he worked in Littleton's studio, creating about 200 pieces of glass for exhibition in the United States. Watching Eisch develop his forms intrigued Littleton. Working with his assistant, Karl Paternoster, Eisch created “small, involved sculptural forms” that he fumed to unify the forms’ surfaces, giving them the iridescence that one sees in Art Nouveau glass. Eisch later resorted to enameling the exteriors of his pieces to strengthen his forms.

The female's beak was long, thin and arched downward, while the male's was short and stout, like that of a crow. Males were long, while females were larger at . The sexes were otherwise similar, with orange wattles and deep metallic, bluish-black plumage with a greenish iridescence on the upper surface, especially about the head. The tail feathers were unique among New Zealand birds in having a broad white band across the tips.

Tasmantrix phalaros is a moth of the family Micropterigidae. It is known from eastern Australia, in wet, upland eucalypt forests of northern New South Wales from Minyon Falls to Narara.Micropterigidae (Lepidoptera) of the Southwestern Pacific: a revision with the establishment of five new genera from Australia, New Caledonia and New Zealand The forewing length is 3.6 mm for males and 3.5 mm for females. The forewing ground colour has a strong purple iridescence.

They have the highest ratio of wing area to body mass and the lowest wing loading of any bird. This has been hypothesized to enable the birds to use marine thermals created by small differences between tropical air and water temperatures. The plumage of males is black with scapular feathers that have a green iridescence when they refract sunlight. Females are black with a white throat and breast and have a red eye ring.

In wavefront-division systems, the wave is divided in space—examples are Young's double slit interferometer and Lloyd's mirror. Interference can also be seen in everyday phenomena such as iridescence and structural coloration. For example, the colours seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film. Depending on the thickness of the film, different colours interfere constructively and destructively.

Chrysochloris asiatica Cape golden mole adult, showing the digging claw, absence of external eye and a hint of the iridescence of the fur. The rhinarium is not obvious in this photograph. Golden moles are small insectivorous burrowing mammals endemic to Southern Africa. They comprise the family Chrysochloridae and as such they are taxonomically distinct from the true moles, family Talpidae, and other mole-like families, all of which, to various degrees, they resemble as a result of evolutionary convergence.

Fresh meat can be cooked for immediate consumption, or be processed, that is, treated for longer-term preservation and later consumption, possibly after further preparation. Fresh meat cuts or processed cuts may produce iridescence, commonly thought to be due to spoilage but actually caused by structural coloration and diffraction of the light.

The forewings are pale buff or cream with ochreous shadings and a sparse dusting of blackish scales and with numerous, rather indefinite blackish or dark steel grey markings. The hindwings are silky cinereous with slight iridescence. The larvae feed on Solanum carolinense. They fold the terminal leaves into round, hollow balls, each of which forms the shelter of a single larva which feeds on the incipient flower buds and the infolded edges of the tender leaves.Can. Ent.

Their heads are small, but their eyes are relatively large, making them look "good-natured". The plumage is soft, resembling fur or velvet on the head and neck. It is mostly black, with purple, green, or bronze iridescence, particularly on the wing coverts and the lower neck. In the best-known taxa the secondary and tertial flight feathers are white, grey, or greenish to black, and hairlike, falling over the lower back, which is the same colour.

Wat Arun Ratchawararam Ratchawaramahawihan ( ) or Wat Arun (, "Temple of Dawn") is a Buddhist temple (wat) in Bangkok Yai district of Bangkok, Thailand, on the Thonburi west bank of the Chao Phraya River. The temple derives its name from the Hindu god Aruna, often personified as the radiations of the rising sun. Wat Arun is among the best known of Thailand's landmarks. The first light of the morning reflects off the surface of the temple with pearly iridescence.

Colville River of Alaska Arctic grayling grow to a maximum recorded length of and a maximum recorded weight of . Of typical thymalline appearance, the Arctic grayling is distinguished from the similar grayling (T. thymallus) by the absence of dorsal and anal spines and by the presence of a larger number of soft rays in these fins. There is a dark midlateral band between the pectoral and pelvic fins, and the flanks may possess a pink iridescence.

They consist of square threads and furrows of equal breadth, and both scored by the longitudinals. On the earlier whorls these spirals disappear before the longitudinals do. And on the base of the shell they become on the outside feebler, closer, and finer, in the middle broader and flatter, and stronger again toward the centre of the shell. The colorof the shell is delicate yellowish, with a horny translucency and exquisite iridescence, which under the lens appears brilliant.

Females also have iridescent red gorgets, though they are usually smaller and less brilliant than the males'. Anna's is the only North American hummingbird species with a red crown. Females and juvenile males have a dull green crown, a grey throat with or without some red iridescence, a grey chest and belly, and a dark, rounded tail with white tips on the outer feathers. These birds feed on nectar from flowers using a long extendable tongue.

Their fourth album, Iridescence, was released on September 21, 2018 and debuted at No. 1 on the Billboard 200 album chart. The album is also the first in their second trilogy, known as "The Best Years of Our Lives". On July 18, 2019, Brockhampton officially announced their fifth album, Ginger, giving it a release date of August. On July 31, they released the first single for the album, titled "I Been Born Again", along with a music video.

This genus has some sexual dichromatism in that the males show green iridescence of the blue upperwing color. By comparison, Arcas has golden-green hindwing undersides dusted with black, with a black band running roughly parallel to the distal wing margin, longer tails, and lacks sexual dichromatism. The female genitals have a long, straight and tubular genital duct with a plain anal end in the type species T. mavors, but variation within the genus is insufficiently studied.Bálint et al.

Graphium sarpedon which contains pterobilin Pterobilin is a blue bile pigment found in Nessaea spp., Graphium agamemnon, G. antiphates, G. doson, and G. sarpedon. It is one of only a few blue pigments found in any animal species, as most animals use iridescence to create blue coloration. Other blue pigments of animal origin include phorcabilin, used by other butterflies in Graphium and Papilio (specifically P. phorcas and P. weiskei), and sarpedobilin, which is used by Graphium sarpedon.

The silktails are small black birds, measuring around and weighing . They are small, dumpy birds with long rounded wings, and a short rounded tail. The plumage of the male is velvet black with metallic blue iridescent spangling on the crown and breast, and silky white lower-back patch that travels most of the length down the tail. The margin of the tail is black, sometimes this tip has the same iridescence as other parts of the body.

The Sulawesi ground dove (Gallicolumba tristigmata) also known as yellow- breasted ground dove is a medium-sized, approximately 35 cm long, olive-brown ground dove with golden forehead, yellow breast, red legs, iridescence bluish- green crown ended with purple patch behind ear coverts, dark brown tail and white below. Both sexes are similar. An Indonesian endemic, this elusive species is distributed to primary rainforests of Sulawesi in Wallacea. The Sulawesi ground dove is a terrestrial bird.

Hildebrandt's starling is in length and weighs . The adult has bright iridescent plumage on its upper body and upper surfaces. As in its relatives, this iridescence is derived from the interference of reflected light from regimented microscopic feather structures and not from pigments. The head is blue as are most of the upperparts, the wings are bronze-green with blue primaries, the throat and upper breast are glossy purple, and the tail is glossy blue-green.

The Sulu bleeding-heart is a medium-sized pigeon with a short tail. Bright metallic green feathers stretch from the forehead and crown down to the mantle and sides of the breast. The scapular feathers are a dark chestnut color and are fringed with iridescence that can appear violet, green, or lilac in different lights. The wing-coverts are also a dark brown, with some of the feathers being ashy-gray at the tip to form a slight wingbar.

|
The plumage of the starling is often brightly coloured due to iridescence; this colour is derived from the structure of the feathers, not from any pigment. Some species of Asian starling have crests or erectile feathers on the crest. Other ornamentation includes elongated tail feathers and brightly coloured bare areas on the face. These colours can be derived from pigments, or, as in the Bali starling, structural colour, caused by light scattering off parallel collagen fibres.

The Splendid astrapia's generic name is Astrapia, which is of the word "Astraipios", meaning lightning flash or glare, referring to the brilliant iridescent plumage of the Astrapias. Its specific name, "splendidissima", means "most splendid", again referring to this particular astrapia's splendid colors. In the past, the splendid astrapia has been placed in its own genus (though very briefly), Calastrapia, which means "beautiful astrapia". Its subspecies helios' specific name simply means "sun", likely referring to its iridescence.

A coppery patch extends from the nape and down along the sides of the neck. This meets a rich green that occupies much of the crown except for the eponymous green forehead patch. Much of the back and dorsal face of the tail are a similar rich green as the green with an iridescence creating a situational alternation between green, teal, and turquoise. The last feature that distinguishes the green-fronted lancebill is its eponymous bill.

Later in '88, Young's solo project, Emerald Vein, released a solo album, Existence, on Sub Rosa. A second Emerald Vein album, Land of the Living (with Barnwell on bass), was issued by Sub Rosa in 1991. Prior to Uzi, Milstein founded the Velvet Underground Appreciation Society in 1977 and edited the club's fanzine, What Goes On. Milstein was part of the collaborative ensemble Between Meals along with Jad Fair (Half Japanese), Moe Tucker (The Velvet Underground), Andy Paley, Erik Lindgren (Birdsongs of the Mesozoic) and David Greenberger (Duplex Planet) and performed percussion, vocals and guitar on their mini-album Oh No I Just Knocked Over a Cup of Coffee, recorded in 1980 and 1982 but released in 1984 on Iridescence Records. Milstein's first solo project, Pep Lester and His Pals, released the Jack-O-Lantern Moon EP on Iridescence in 1984, which included musical contributions from Fair, Lindgren, Greenberger, Christmas members Michael Cudahy and Liz Cox (both later of Combustible Edison), and Mission of Burma members Roger Miller and Martin Swope, and mixing on one track by Willie "Loco" Alexander.

Apaturina erminea has a wingspan of about , and males measure marginally larger than females. The uppersides of the forewings are black with an iridescent blue-green base, two white small spots at the apex and a diagonal series of pale yellow patches across each wing. The uppersides of the hindwings are completely iridescent blue green in males, or chestnut brown in females, with an eyespot on each wing. The undersides are quite similar but the basic color is grayish brown, without iridescence.

Those caused by rocket exhausts tend to show colours other than silver or blue, because of iridescence caused by the uniform size of the water droplets produced. Noctilucent clouds may be seen by observers at a latitude of 50° to 65°.Gadsden (1995), p.8. They seldom occur at lower latitudes (although there have been sightings as far south as Paris, Utah, Italy, Turkey and Spain), and closer to the poles it does not get dark enough for the clouds to become visible.

The adult brimstone travels to woodland areas to spend seven months overwintering. In spring when their host plants have developed, they return to the wetlands to breed and lay eggs. Both the larval and adult forms of the common brimstone have protective coloration and behaviour that decreases their chances of being recognised and subsequently preyed upon. The adult common brimstone has sexual dimorphism in its wing coloration: males have yellow wings and iridescence while females have greenish-white wings and are not iridescent.
|
|
In males, iridescence is indicated in that the wing pattern appears to visually change depending on the position of the ultraviolet light shone onto the wing. At some angles, a male pattern is seen, while at other angles, a female lack of pattern is seen. This is referred to as the "gynandromorphic effect." This demonstrates that the pattern appears to be optical, rather than pigmental, as the effect is only seen at certain angles and distances of light and changes with positions.

|
The pattern is first mapped out, followed by the meticulous application of multiple layers of paint and finished with pearl iridescence. I really don't fully see what has been created until the piece is saturated with Lascaux matte varnish, which intensifies and further activates the excavated colors from the various strata. Light is absorbed through the rugged and uneven layers of Mud, like a bas relief, casting shadows and highlights. Contrasted with this earthiness is the pearlescent grid, shimmering with kinetic energy.

Infection may involve the inner thighs and genital areas, as well as extending back to the perineum and perianal areas, and the rash can spread to any part of the body and is considered highly contagious. Affected areas may appear reddish, tan, or brown, with flaking, rippling, peeling, iridescence, or cracking skin. The acute infection begins with an area in the groin fold about a half-inch across, usually on both sides. The area may enlarge, and other sores may develop.

Christmas beetle is a name commonly applied to the Australian and South African beetle genus Anoplognathus. They are known as Christmas beetles because they are abundant in both urban and rural areas close to Christmas. Christmas beetles are large (20–30 mm long) members of the scarab family that are noisy and clumsy fliers, similar to the cockchafers of Europe. They typically have elytra that are dark or light brown, or green, while some species have a green-yellow iridescence.

Male C. eurytheme hindwings demonstrate an ultraviolet reflectance pattern while female C. eurytheme hindwings demonstrate ultraviolet absorbing patterns. According to studies, these ultraviolet reflecting wing scales found in males also contain pterin pigments that absorb wavelengths below 550 nm. Although this may seem paradoxical, the pterin pigments have been found to decrease the amount of diffuse ultraviolet reflectance that comes from the wing scales. By suppressing the diffuse ultraviolet reflectance, the directionality and spectral purity of the iridescence is heightened.

|
The first pair bear long iridescent hairs. These act as a diffraction grating and cause iridescence by the diffraction of light in a manner similar to that which happens in a hologram. Another unusual feature of this ostracod is the possession of a lateral eye which takes the form of a hairy flap of skin containing flecks of photosensitive pigment. This eye is unable to form a proper image but is able to detect differences in the intensity of light.

|
Chromatophores come in a variety of types based on the color they correspond to. Chromatophore types include xanthophores (responsible for yellow coloration), erythrophores (responsible for red coloration), iridophores (responsible for iridescence), leucophores (responsible for white coloration), melanophores (responsible for black coloration), and cyanophores (responsible for blue coloration). The skin of wild common leopard geckos contains xanthophores (yellow) and melanophores (black spots). Designer common leopard geckos may possess erythrophores and leucophores since commercial breeding and artificial selection have allowed novel coloration to arise.

Staffordshire pottery jug, c. 1815 Lustreware or Lusterware (respectively the spellings for British English and American English) is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen. The technique of lustreware on pottery was first developed in Mesopotamia (modern Iraq) in the early 9th century.

When flying, it appears heavy and large-tailed, although its flight is rapid and direct. The common wood pigeon had a poorly defined Madeiran subspecies, Columba palumbus maderensis. This was paler than the trocaz pigeon and had white wing patches and a more extensive green iridescence on the nape, but it became extinct before 1924. Bolle's pigeon is more similar in appearance to the trocaz pigeon, although it lacks the whitish neck patch and has a more extensively pink breast.

"Death Valley '69" is a song by American alternative rock band Sonic Youth and featuring Lydia Lunch. The song was written and sung by Thurston Moore and fellow New York musician Lunch, and recorded by Martin Bisi in 1984. A demo version of the song was released in December 1984 on Iridescence Records. A re-recorded version was released in EP format with different artwork in June 1985; this version was featured on their second studio album, Bad Moon Rising.

The Taveuni silktail is a small black bird, measuring around and weighing . It is a small, dumpy bird with long rounded wings, and a short rounded tail. The plumage of the male is velvet black with metallic blue iridescent spangling on the crown and breast, and silky white lower-back patch that travels most of the length down the tail. The margin of the tail is black, sometimes this tip has the same iridescence as other parts of the body.

Nonbreeding adult P. p. resplendens on Morro Rock (California, United States) This is a smallish cormorant which measures in length, with a wingspan of about 3.3 ft (1 meter) and a weight of 52–86 oz (1,474–2,438 g) when fully grown. Adults in nonbreeding plumage are all-black with a metallic iridescence. In breeding plumage they grow two short crests (one on top of the head and one at the nape), white thighs, and scattered white filoplumes on the head and neck.

Iridescent clouds are a diffraction phenomenon caused by small water droplets or small ice crystals individually scattering light. Larger ice crystals do not produce iridescence, but can cause halos, a different phenomenon. Irisation is caused by very uniform water droplets diffracting light (within 10 degrees from the Sun) and by first order interference effectsColor and Light in Nature By David K. Lynch, William Charles Livingston, Page 133 (Beyond about 10 degrees from the Sun). It can extend up to 40 degrees from the Sun.

The species is a part of the Iridomyrmex purpureus group, and is among the most familiar ant the Australian public is affiliated with. A typical worker is a medium-sized ant in comparison to its relatives within its genus, and will have a broad head, with a blue or yellowish-green iridescence on the workers gaster. These ants in Sydney are different in variation and can be distinguished by their dark coloured appearance and small heads, which isn't normal when compared to other colonies elsewhere in Australia.

The lateral line contains 46-56 pored scales. This species is mainly dusky-green in colour with has a green iridescence which fades to silver-white on the belly. There are four broad dark, horizontal stripes along the flanks, a big black spot on the dorsal fin and dusky stripes on the tail. The juveniles are brown in colour and their stripes are darker and have white spots which run in lines in the paler areas between the dark stripes and they have a striped tail.

The female also displays her plumage to ward off female competition or signal danger to her young. Green peafowl differ from Indian peafowl in that the male has green and gold plumage and black wings with a sheen of blue. Unlike Indian peafowl, the green peahen is similar to the male, but has shorter upper tail coverts, a more coppery neck, and overall less iridescence. The Congo peacock male does not display his covert feathers, but uses his actual tail feathers during courtship displays.

An occurrence of altocumulus and cirrocumulus cloud iridescence Sunset reflecting shades of pink onto grey stratocumulus clouds. The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum. Tiny particles of water are densely packed and sunlight cannot penetrate far into the cloud before it is reflected out, giving a cloud its characteristic white color, especially when viewed from the top.

|
Early scientific names mostly used Latin or Greek descriptors, for example the type species Maratus amabilis (1878) refers to the friendly or pleasant Maratus. Maratus volans (1874) means the flying Maratus, reflecting the mistaken belief this species (and indeed the genus) could fly by means of its extended abdominal flap. We now know they cannot fly and the flap is used in courtship or (in at least one case) ritualised combat. Maratus chrysomelas refers to the golden yellow iridescence of the abdomen when viewed at some angles.

For instance, the chiral self-assembly of cellulose inspired by the Pollia condensata berry has been exploited to make optically active films. Such films are made from cellulose which is a biodegradable and biobased resource obtained from wood or cotton. The structural colours can potentially be everlasting and have more vibrant colour than the ones obtained from chemical absorption of light. Pollia condensata is not the only fruit showing a structural coloured skin; iridescence is also found in berries of other species such as Margaritaria nobilis.

Iridescent male common grackle Adult common grackles measure from in length, span across the wings, and weigh . Common grackles are less sexually dimorphic than larger grackle species, but the differences between the sexes can still be noticeable. The male, which averages , is larger than the female, at an average of . Adults have a long, dark bill, pale yellowish eyes, and a long tail; their feathers appear black with purple, green, or blue iridescence on the head, and primarily bronze sheen in the body plumage.

Iridescence was officially released on September 21, consisting of fifteen new songs, including the revamped version of "Tonya" without Sullivan and Beatty, who lent vocals during the debut performance of the song four months earlier. It debuted at number one on the US Billboard 200 on September 30, 2018, becoming BROCKHAMPTON's first chart-topping album. In January 2019, the band received their first ever nomination for the "Best International Group" at the BRIT Awards, which took place at The O2 Arena on February 20, 2019.

Iridescent Begonia leaf Many groups of plants have developed iridescence as an adaptation to use more light in dark environments such as the lower levels of tropical forests. The leaves of Southeast Asia's Begonia pavonina, or peacock begonia, appear iridescent azure to human observers due to each leaf's thinly layered photosynthetic structures called iridoplasts that absorb and bend light much like a film of oil over water. Iridescences based on multiple layers of cells are also found in the lycophyte Selaginella and several species of ferns.

Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor and is easily distinguished from that of genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them.

Tempering colors are produced when steel is heated and a thin film of iron oxide forms on the surface. The color indicates the temperature the steel reached, which made this one of the earliest practical uses of thin-film interference. Iridescent interference colors in an oil film Iridescence caused by thin-film interference is a commonly observed phenomenon in nature, being found in a variety of plants and animals. One of the first known studies of this phenomenon was conducted by Robert Hooke in 1665.

Precious opal displays play-of-color (iridescence), common opal does not. Play-of-color is defined as "a pseudo chromatic optical effect resulting in flashes of colored light from certain minerals, as they are turned in white light." The internal structure of precious opal causes it to diffract light, resulting in play-of-color. Depending on the conditions in which it formed, opal may be transparent, translucent, or opaque and the background color may be white, black, or nearly any color of the visual spectrum.

In the deeply pigmented centre of the flower, the surface features striations, which have been the subject of controversy about whether they act as a diffraction grating, creating iridescence. The pollinated but unripe seedpods look like oriental paper lanterns, less than an inch across, pale green with purple highlights. The flowers of the Hibiscus trionum can set seed via both outcrossing and self-pollination. During the first few hours after anthesis, the style and stigma are erect and receptive to receive pollen from other plants.

The forewings measure for the males and for the female. The wings' underside for both sexes are the same: they are a pale brownish gray with a slight yellow iridescence and with a pattern of red, eye- like markings on the hindwing around the M3 and Cu1 cells (see the Comstock–Needham system of insect wing nomenclature). The upper surface of the male wings are a purple metallic color. The upper surface of the female forewing is dark brown with some blue tint near the basal area.

The lower valve of Anomia simplex remains an off-white color, whereas the upper valve of these shells can range from shiny lemon yellow, golden, brown, silvery black, and pale buff. The characteristic iridescence of these common bivalve mollusks is retained even well after death. Additionally, common jingle shells are very thin and their shells can range from roughly circular to broadly oval-shaped. Overall, the shell is often translucent, smooth, and displays various growth lines which can mirror the substrate in which they lived on.

Unlike their congener's bill, they have a pale, ivory-ish colored, downcurved bill. The ornaments present on the male are relatively extensive pectoral feathers in rows on the sides of the breast and belly. The pectoral feathers highest on the breast (on each side) are dark greyish with coppery red to reddish iridescent tips; the rest of the pectoral plumes on the sides have more of a greenish-copper iridescence to their tips. The female of this species is, for the most part, similar to the male.
|
|
However, the inner layer in the great majority of mollusc shells is porcellaneous, not nacreous, and this usually results in a non-iridescent shine, or more rarely in non-nacreous iridescence such as flame structure as is found in conch pearls. The outer layer of cultured pearls and the inside layer of pearl oyster and freshwater pearl mussel shells are made of nacre. Other mollusc families that have a nacreous inner shell layer include marine gastropods such as the Haliotidae, the Trochidae and the Turbinidae.
|
|
While its tail is relatively short, a few other species from the genus have equally short tails (e.g. the green-tailed emerald). The male's bird's whole crown and belly are a solid glittering emerald green, with iridescence, the back a shining green, while the feathers of his short tail are a darker olive green. The female bird also has a shining green back, but her crown is nearer to brown in colour, while her underparts are grey, and she has a short white streak behind her eye.

N. eques Most species are slender, pencil-shaped fish ranging in size from under 1 to about 2 in long. N. marginatus, N. rubrocaudatus, and N. mortenthaleri possess shortened, blockier outlines reminiscent of pencil stubs. All but one species, Nannostomus espei, possess one to five horizontal black or brown stripes with gold or silver iridescence appearing dorsal to the primary stripe. Most also display red, orange, or maroon highlights in their fins, and many have flashes of these colors on their flanks, as well.
|
|
The brightness of the colours is neither the product of iridescence (except in the American kingfishers) or pigments, but is instead caused by the structure of the feathers, which causes scattering of blue light (the Tyndall effect). In most species, no overt differences between the sexes exist; when differences occur, they are quite small (less than 10%). The kingfishers have long, dagger-like bills. The bill is usually longer and more compressed in species that hunt fish, and shorter and more broad in species that hunt prey off the ground.

The variety chiastolite commonly contains dark inclusions of carbon or clay which form a cruciform pattern when shown in cross-section. This stone was known at least from the sixteenth century, being taken to many European countries, as a souvenir, by pilgrims returning from Santiago de Compostela. A clear variety found in Brazil and Sri-Lanka can be cut into a gemstone. Faceted andalusite stones give a play of red, green, and yellow colors that resembles a muted form of iridescence, although the colors are actually the result of unusually strong pleochroism.

The plumage is much drabber than the other brightly coloured sunbirds, is the same for both sexes, and contains no iridescence. The uppersides of most species are olive-green and the undersides dull white or yellow - in half the species the undersides are streaked. The most atypical spiderhunter plumage is that of the Whitehead's spiderhunter, which is dark brown with white streaking on the undersides and back and a yellow rump. The calls of the spiderhunters are very simple, typically a metallic chip which is repeated multiple times to form the song.

The purple sunbird (Cinnyris asiaticus) is a small bird in the sunbird family found mainly in South and Southeast Asia but extending west into parts of the Arabian peninsula. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers. The males can appear all black in harsh sunlight but the purple iridescence is visible on closer observation or under good light conditions.

Across twelve tracks, the rap collective is noticeably more controlled and concise." Some reviewers were more lukewarm in their reception to the album. In the review for Clash, Debbie Ijaduola called the album "new ground for Brockhampton, and a gentle nudge to others, urging them to go on their own paths of rediscovery and explore their roots. Thing is, we might need a bit more than a gentle nudge." HipHopDX reviewer Daniel Spielberger wrote, "Iridescence proved that the group could survive Vann’s abrupt departure, Ginger exposes their creative limitations.

The colouration of butterfly wings is created by the scales which are pigmented with melanins that give them blacks and browns, but blues, greens, reds and iridescence are usually created not by pigments but the microstructure of the scales. This structural coloration is the result of coherent scattering of light by the photonic crystal nature of the scales.Vukusic, P., J.R.Sambles, and H. Ghiradella (2000) Optical Classification of Microstructure in Butterfly Wing-scales. Photonics Science News, 6, 61-66 The scales cling somewhat loosely to the wing and come off easily without harming the butterfly.

The signing was part of SST's efforts to expand its scope beyond punk rock and hardcore. They released two albums, Beyond Barbecue (which was first planned for release on Iridescence Records) in 1986 and Sasquatch Rock in 1987, which featured Ginn on the song March of the Melted Army Men. They also appeared on three SST Records compilations during that period and two New Alliance Records compilations after they split in 1987. The band split in 1988 and sporadically reunited to play some shows and write new material that was never released.

Like other Moxostoma, the blacktail redhorse has a long and cylindrical body. It is gold to bronze on the upper half with a silver-green iridescence, and is a silver yellow to white on the lower half. The caudal and lower fins are red, with a black stripe on the lower half of the forked caudal fin, which is normally larger than the upper half. The edge of the dorsal fin is usually concave, and the fin is a dusky grey on the lower half and more red on the upper half.

Mature males are very dark, almost black, sometimes with a blue-green iridescence, and the white spots are very conspicuous. The eye is bright yellow and crossed by an oblique bar. Mature males have elongated filamentous tips to the dorsal and anal fins, but do not have enlarged jaws (in contrast to species like Oreochromis mossambicus). Young fishes have numerous small slender tricuspid teeth, but they become stouter in larger fish, and sometimes bicuspid. Overall, there are usually 4–6 rows of teeth, occasionally up to 8 in larger fish.

The bronze mannikin is one of the smallest munia species, measuring 9–10 cm in length and weighing 7–12 grams. The adult is a compact bird with a short black tail, and stubby black and pale grey (not distinctly bluish) mandibles. It is black to brownish black on the head, chin, throat and center of the chest, with some purple-green iridescence on the face and sides of the breast. It has greyish brown upper parts and white underparts with irregular barring on the flanks and rump.

In New Zealand, abalone is called paua (, from the Māori language). Haliotis iris (or blackfoot paua) is the ubiquitous New Zealand paua, the highly polished nacre of which is extremely popular as souvenirs with its striking blue, green, and purple iridescence. Haliotis australis and Haliotis virginea are also found in New Zealand waters, but are less popular than H. iris. Like all New Zealand shellfish, recreational harvesting of paua does not require a permit provided catch limits, size restrictions, and seasonal and local restrictions set by the Ministry for Primary Industries (MPI) are followed.

The Campbell teal or Campbell Island teal (Anas nesiotis) is a small, flightless, nocturnal species of dabbling duck of the genus Anas endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the brown teal. The plumage is similar to that of the Auckland teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by Poa tussock grass, ferns and megaherbs.

California corbina are uniformly grey in color with some iridescence and have an elongated and slightly compressed body shape in comparison to other croakers. Like all members of the genus Menticirrhus, the California corbina lacks a swim bladder and is unable to produce a croaking sound. It is believed that the loss of the swim bladder evolved to facilitate living in a turbulent environment. This species and the yellowfin croaker are the only two of the eight coastal croakers found in California waters to exhibit a single barbel on the lower jaw.

All these species have generally black plumage with varying amounts of green and blue iridescence. The female plumage of the dimorphic species is typically drab to blend in with their habitat, unlike the bright attractive colours found on the males. Younger males of these species have female-like plumage, and sexual maturity takes a long time, with the full adult plumage not being obtained for up to seven years. This affords the younger males the protection from predators of more subdued colours, and also reduces hostility from adult males.

Skeleton of American crow (Corvus brachyrhynchos) on display at the Museum of Osteology Corvids are large to very large passerines with a robust build, strong legs and all species except the pinyon jay have nostrils covered by bristle-like feathers. Many corvids of temperate zones have mainly black or blue coloured plumage; however, some are pied black and white, some have a blue-purple iridescence and many tropical species are brightly coloured. The sexes are very similar in color and size. Corvids have strong, stout bills and large wingspans.

The polymorphy, the particular crystallization, the iridescence and the amazing colours of the minerals surprise the visitors upon arrival. Aragonites, azurites, smithsonites from Lavrion are classified among the most beautiful of the world, whilst major Museums abroad would be proud to behold among their exhibits, samples of annabergite, spangolite, takovite, ktenasite, kapellasite, glaucocerinite, a.o., such as presented here. The collection of the museum The collection of the museum also comprises ancient and modern miners’ tools, together with lead “turtles” – produced for commercialization – their moulds and other products derived from the smelting process.

Tasmantrix thula is a moth of the family Micropterigidae. It is known from eastern Australia, where it is known from northern Queensland, from Devils Thumb and Mossman Gorge in the north to Mission Beach and from Herberton State Forest to Mission beach.Micropterigidae (Lepidoptera) of the Southwestern Pacific: a revision with the establishment of five new genera from Australia, New Caledonia and New Zealand The forewing length is 3.2 mm for males and 3.8 mm for females. The forewing ground colour is dark blackish-brown with strong purple iridescence.

The shell's structure is distinctive: sinuous bands of blue, green, and rose iridescence are delineated by dark brown lines of conchiolin, a proteinaceous material that holds the shell together. The luster of abalone shell is silky rather than the near vitreous luster of polished ammolite, and the colors of the two materials do not closely approximate. However, some abalone shell has been dyed and given a transparent cap of synthetic quartz, forming a doublet in the same fashion as ammolite. These doublets are perhaps the most deceptive, and have also been used to imitate opal.
|
|
The wingspan is about 28 mm. The forewings are dark brown, with violet iridescence and a suffused dark fuscous median longitudinal streak from the base to the apex, and one along the fold to a spot beneath the middle of the wing followed by a white dot, between these a band of greyish-violet suffusion extends to the termen. There is a transverse suffused dark fuscous spot from the upper margin of the median streak at three-fifths. The hindwings are grey, paler and subhyaline towards the base.

Most commonly confused with diffraction gratings are the iridescent colors of peacock feathers, mother-of-pearl, and butterfly wings. Iridescence in birds, fish and insects is often caused by thin-film interference rather than a diffraction grating. Diffraction produces the entire spectrum of colors as the viewing angle changes, whereas thin-film interference usually produces a much narrower range. The surfaces of flowers can also create a diffraction, but the cell structures in plants are usually too irregular to produce the fine slit geometry necessary for a diffraction grating.

Later concerts in this tour included additional songs from Two Hearts."Jackie Evancho Making Tour Stop in Hometown of Pittsburgh", Pittsburgh Today Live, KDKA-TV, February 21, 2017 at 4:45 Reviewing her holiday show in Troy, New York, Steve Barnes of the Times Union noted that Evancho performed more than 20 numbers, including four holiday songs. He wrote that her voice is "an instrument of pristine beauty. It peals with the purity of bells and lofts tones that shimmer with celestial iridescence" but that her performance lacks "an apparent interpretive style or emotional connection to the material".

Between 1917 and 1922 she collaborated with Victor Onslow on the colour and iridescence in insect scales. In 1925 she produced a second, substantially revised edition of her book The Anthocyanin Pigments of Plants, updated for the substantial developments in the field since the first 1916 edition. In combining genetics and biochemistry she became one of the first biochemical geneticists and paved the way for the later successes of such seminal investigators as Edward Tatum and George Beadle. In 1926 she was one of the first women appointed as a University Lecturer at Cambridge, in plant biochemistry in the biochemistry department.

Glassware washed by dishwashing machines can develop a white haze on the surface over time. This may be caused by any or all of the below processes, of which only the first is reversible: ; Deposition of minerals: Calcium carbonate (limescale) in hard water can deposit on surfaces when water dries. The deposits can be dissolved by vinegar or another acid. ; Silicate filming, etching, and accelerated crack corrosion: This film starts as an iridescence or "oil-film" effect on glassware, and progresses into a "milky" or "cloudy" appearance (which is not a deposit) that cannot be polished off or removed like limescale.

The forewings are pale yellow ochreous, with silvery iridescence. The basal fourth of the costa has small black marks and there is a dark fuscous streak along the costa from one-fourth to three-fourths, marked with one or two pale strigulae before the middle, and triangularly expanded beyond the middle. There is a broad dark fuscous streak along the dorsum from the base to the tornus, the upper edge forming two rounded undulations which reach halfway across the wing, the crest of the first is suffused with blackish. There are also some scattered fuscous scales and slight suffusion in the disc.

The butterflies often have the appearance of small satyrids or Thecla species; as for instance Euselasia eutychus resembles (particularly beneath) exactly Euptychia helle flying in the same locality, or Thecla themathea; or Euselasia clithra resembles Euptychia chloris and so on. On the upper surface there is often a very bright reflection of a shining power otherwise not found in any lepidopteran and of a truly wonderful iridescence. The larvae are somewhat of the shape of a woodlouse, very brightly coloured, behind the head there are two points. The pupae are covered with fine, fluffy hairs like the larvae, green, held by a belt.

On July 27, the group released the single "1997 Diana", accompanied by a music video. Later that day the song was featured on the third episode of Things We Lost in the Fire Radio, alongside the unfinished track "Don't Be Famous". On August 26, 2018, the group announced that a new album titled Iridescence, recorded over ten days in Abbey Road Studios, would be released in September. The band also announced dates of their "i'll be there" tour, which began on October 3, 2018 in Mesa, Arizona, concluding on December 6, 2018 in Las Vegas, Nevada.

A paua shell bracelet To Māori, pāua are recognised taonga, or treasure, esteemed both as kaimoana (seafood) and as a valued resource for traditional and contemporary arts and crafts. Pāua are frequently used to represent the eyes in Māori carvings and traditionally are associated with the stars or whetū, the symbolic eyes of ancestors that gaze down from the night sky. The pāua is iconic in New Zealand: its black muscular foot is considered a delicacy, and the shell is frequently used in jewellery. Highly polished New Zealand pāua shells are extremely popular as souvenirs with their striking blue, green, and purple iridescence.

For instance, the disorder called albinism affects the level of melanin production in animals. Pigmentation in organisms serves many biological purposes, including camouflage, mimicry, aposematism (warning), sexual selection and other forms of signalling, photosynthesis (in plants), as well as basic physical purposes such as protection from sunburn. Pigment color differs from structural color in that pigment color is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well.

When the wings are opened either during displays or for flight, a narrow band of very bright unfeathered skin is visible along the underside of the forearm. This band has been variously described as being "neon, orange-red", "like a red-gold jewel", and "almost glowing" when seen at close range. Small nestlings are pale grey with buffy down on the neck, and a black crown. At fledging age, the immature bird is identical to the adult except for a feathered forehead, much lesser iridescence on feathers, and much longer and fluffier feathers on the neck.

Kennedy creates prints, posters and postcards from handset wood and metal type, oil-based inks, and eco-friendly and affordable chipboard. Many of the posters are inspired by proverbs, sayings, and quotes Kennedy locates or potential clients provide. Using hand presses, he “produces large editions of wildly colourful, typographically- driven posters on inexpensive chipboard stock, posters which are often so riotously layered with vibrant colours of ink as to retain a wet iridescence and tackiness years after they were printed. His working method often involves overprinting multiple layers of text ...resulting in no two prints being truly identical.

Structure of nacre layers, wherein aragonite plates are separated by biopolymers, such as chitin, lustrin and silk-like proteins Electron microscopy image of a fractured surface of nacre The unique luster of pearls depends upon the reflection, refraction, and diffraction of light from the translucent layers. The thinner and more numerous the layers in the pearl, the finer the luster. The iridescence that pearls display is caused by the overlapping of successive layers, which breaks up light falling on the surface. In addition, pearls (especially cultured freshwater pearls) can be dyed yellow, green, blue, brown, pink, purple, or black.

Turnaround video of an adult female specimen at Naturalis The adult female passenger pigeon was slightly smaller than the male at in length. It was duller than the male overall, and was a grayish-brown on the forehead, crown, and nape down to the scapulars, and the feathers on the sides of the neck had less iridescence than those of the male. The lower throat and breast were a buff-gray that developed into white on the belly and undertail-coverts. It was browner on the upperparts and paler buff brown and less rufous on the underparts than the male.

Of the hundreds of surviving skins, only one appears to be aberrant in coloran adult female from the collection of Walter Rothschild, Natural History Museum at Tring. It is a washed brown on the upper parts, wing covert, secondary feathers, and tail (where it would otherwise have been gray), and white on the primary feathers and underparts. The normally black spots are brown, and it is pale gray on the head, lower back, and upper-tail covert feathers, yet the iridescence is unaffected. The brown mutation is a result of a reduction in eumelanin, due to incomplete synthesis (oxidation) of this pigment.

Like many of the birds of paradise, adult riflebirds are sexually dimorphic, with adult males being entirely velvety black and females being mostly shades of brown. Adult females are also slightly smaller and have longer bills. Adult males are larger in L. magnifica (31 cm long, 160g; L.intercedens is similarly sized), smaller in L. paradisea (28 cm, 135g), and smallest in L. victoriae (22 cm, 105g). Adult male riflebirds of the four species are similar in appearance: all are entirely velvety black with lighter underparts, iridescence on the head, upper throat and centre of the tail and yellow mouth and gape.

The reviewer enjoyed both "an effective and judicious deployment of swears, always enjoyable," and "some more nuanced shades." "Houghton has a wonderful singing voice, gifted with subtlety in its delivery and a great range. And she uses it to convey a range of emotions, subtly as well as furiously," she added, giving the album the 8.5/10 rating. "While she possesses a silvery voice that would sound right at home on album after album of Yours Truly's ethereal folk-pop, her transformation from Beth Jeans Houghton's soap bubble iridescence to Du Blonde's biker jacket toughness is surprisingly effective," writes Allmusic.

The metanotal area is also longer and more distinct in Paratrechina zanjensis, being more strongly separated from the mesonotum and propodeum. Paratrechina zanjensis has erect macrosetae that are dark rather than pale as in Paratrechina longicornis, the body is glossier, and largely lacks the opalescent sheen / iridescence that is characteristic of Paratrechina longicornis. Paratrechina zanjensis is superficially similar to Nylanderia silvula, but can readily be distinguished from this species by its mandibular dentition (5 teeth in Paratrechina, 6 in Nylanderia), larger eyes, longer limbs and less strongly domed propodeum. Male and queens for Paratrechina zanjensis remain unknown.

An argument has been made that shot silk was also described as purpura at this time, the Latin word mainly applied to purple although there are multiple references to purpura being red, green and black-and-red, as well as "varied". Purpura is also used to mean iridescence and the play of light, and contemporary descriptions exist indicating that the textile purpura was a type of silk distinct to other silks in assorted colours. It has also been suggested that illuminations in the Lindisfarne Gospels of c.700 show garments of shot silk being worn by the Four Evangelists.

Though this characteristic can also be seen in people of Northwestern Europe, it is less common.The Distribution of Anthropological Traits in Europe, Bertil Lundman: The Races and Peoples of Europe (New York 1977) People of Celtic heritage in Ireland with such traits are sometimes known as the "Black Irish". Hair is naturally reflective, so black hair is not completely dark in bright light. However, the darkest shade will not have a warm, neutral tone but a sheen which can seem almost blue, like the iridescence of a raven's wing; hence, sometimes referred to as raven- black.

There was a concentrated series of works in the early 1970s influenced by Minimalism (Minimal Art). Among other things, he created transparent, folded canvases that incorporated superimposed folded shapes, form elements – cut out and therefore definitively liberated from their original context: floating particles in a solidified fluid, like scattered inlays in radiant amber. The colour only becomes apparent in the light and iridescence, further differentiated by the surface. As in other still haptic works, the first configurations are not created through construction but through attachments that allow forms to emerge through a mechanical process, almost by chance and in a semi-experimental way.

Young described iridescence as the result of interference between reflections from two or more surfaces of thin films, combined with refraction as light enters and leaves such films. The geometry then determines that at certain angles, the light reflected from both surfaces interferes constructively, while at other angles, the light interferes destructively. Different colours therefore appear at different angles. In animals such as on the feathers of birds and the scales of butterflies, interference is created by a range of photonic mechanisms, including diffraction gratings, selective mirrors, photonic crystals, crystal fibres, matrices of nanochannels and proteins that can vary their configuration.

Viva Pataca made his Asian racing debut at Sha Tin Racecourse in Hong Kong on 1 January 2006, finishing third in the 1400 metre Chang Jiang Handicap. Two weeks later, under new jockey Christophe Soumillon, he won the 1600 metre New Asia Road Handicap then in mid February won the Chukyo Handicap. In late March, Viva Pataca won his first Group One race when he gave trainer John Moore his second win in the Hong Kong Derby. In April, jockey Gerald Mosse rode him to a sixth-place finish behind winner Iridescence in the Queen Elizabeth II Cup.

The matrix is not visible in finer grades, and there should be no foreign minerals breaking up or diminishing the iridescence. The thickness of the ammolite layer is also an important factor: after polishing, the ammolite is only 0.1–0.3 millimeters thick. The rarest and most valuable are thick enough to stand alone, with only a thin portion of its original matrix (not exceeding 1.5 mm); but the vast majority require some sort of supportive backing. Other treatments are also commonly undertaken; all other factors being equal, the less treatment an ammolite gem has received, the more valuable it is.

Astrapia nigra. Museum specimen Male Arfak Astrapia specimen at the Naturalis Biodiversity Center. The Arfak Astrapia is the third largest of its genus, being approximately 76 cm long, including the tail. The male has a black head with a bluish-purple sheen, or iridescence, an elongated jet- black nape crests extending up along the sides of the neck up to the eyes on each side, a shiny, metallic greenish-yellow cape from the mantle up to the nape, very black, dense and elongated upper breast feathers, and an almost exaggeratedly long tail almost two times the length of its body.

The wingspan is 13–15 mm. The forewings are ferruginous with a very oblique wedge-shaped yellow-whitish patch from near the base of the costa to the fold, sometimes suffused with ground colour beneath. A thick dark red-brown longitudinal streak is found from the base of the dorsum to one-third, surrounded with violet iridescence, followed by a subdorsal spot of leaden suffusion. There is a violet-silvery white oblique trapezoidal patch resting on the middle of the costa, one angle reaching three-fourths across the wing, the other forming a short acute projection posteriorly near the costa.

The significance of what is happening is often placed within the memory or in the inner contemplation of what is described. This focus on the relationship between experience, memory and writing and the radical de-emphasizing of the outward plot, have become staples of the modern novel but were almost unheard of in 1913. Roger Shattuck elucidates an underlying principle in understanding Proust and the various themes present in his novel: > Thus the novel embodies and manifests the principle of intermittence: to > live means to perceive different and often conflicting aspects of reality. > This iridescence never resolves itself completely into a unitive point of > view.

Illustration by John Gould (probably from stuffed specimens) Illustration in habitat by Gustav Mützel The tooth-billed pigeon is a medium-sized, approximately 31 cm long, dark pigeon with reddish feet and red bare skin around the eye. The underparts, head and neck are greyish with a slight blue-green iridescence, and the tail, wings- coverts and tertials are rufous chestnut, while the remaining remiges are blackish. It has a large, curved, and hooked bright red bill with tooth-like projections on the lower mandible. Both sexes are similar, but the juvenile is duller with a browner head, with a black bill with only the base a pale orange.

Male Wilson’s Birds of Paradise are the most colorful of all the species within the family, possessing a veritable rainbow of color. This remarkable example of hue and iridescence possesses all of the primary colors (and more) in different ways. The baby blue hue of its head is skin, not feathers, and is the result of structural color absent in any other member of birds of paradise. Yellow on the nape of its neck, followed by the crimson on its back are consistent, pigmented colors, present year-round. Its quirky, “handlebar-mustache-shaped” tail feathers are brilliantly iridescent, reflecting light to produce intense color to the eye of the beholder.

Before any symptomatic manifestation of colony collapse disorder, various physio- pathological traits may serve as biomarkers for colony health as well as predict CCD status. Bees of collapsing colonies tend to have a soft fecal matter, half-filled rectums, rectal enteroliths (rectal stones), and Malpighian tubule iridescence. The defective rectum indicates nutritional disruption or water imbalance, whereas rectal enteroliths suggest a malfunction of excretory physiology which might further lead to constipation and poor osmoregulation in CCD bees. These traits express at various degrees across four bee age groups (newly emerged bees, nurse bees, non-pollen foragers, and pollen foragers) and were confirmed not to be associated with age.

The Harlow Block, built in an Italianate style, exemplifies late nineteenth century vernacular commercial architecture. The rectangular building is three stories tall and constructed of red Lake Superior sandstone of a type locally known as "raindrop" for its iridescence. The building measures extends 75 feet along Front Street and 146 feet along Washington Street, and is built on a sloping lot such that the ground floor is substantially covered in the rear of the building. The main facade is separated by pilasters into four bays, three wider ones which are substantially identical, and a narrower one, located second from the right, housing the entrance.

" In a review for DIY, Elly Watson called the album the band's "most mature and concise work to date," which "deliver some of their most raw and unfiltered verses so far." Sophie Walker reviewed the album for The Line of Best Fit, where she claimed that "Ginger yields a sound that is more emotionally evolved than any album thus far. Where The Saturation Trilogy was raw youthfulness and Iridescence was loaded with erratic expression, Ginger is, at last, the coherence we have been searching for. Here is a band who have had the chance to breathe, to live, to process – the result is Brockhampton have finally come of age.

" David Skipworth was also receptive in an appraisal for The New Zealand Herald, stating it "showcases the myriad directions in which the group could go and ultimately reassures fans that Brockhampton are here to stay." Reviewing the album for NME, Will Richards wrote "Brockhampton push themselves forward gently in musical terms... [The album] is the sound of the lyrical weight of ‘Iridescence’ being forcibly lifted off the band, with auto-tuned melodies floating around a catchy, snappy beat. It’s utter bliss." In the review for Variety, Brandom Yu declared that "With 'Ginger,' their fifth record in just over two years, they’ve presented their tightest and potentially most memorable album yet.

Cheke and Hume have suggested that the French word (bécasse) from Dubois' original description, usually translated to "woodcock", could also mean oystercatcher, another bird with a long, straight, but slightly more robust, bill. They have also pointed out that the last sentence is mistranslated, and actually means the bird could be caught by running after it. The bright colouration of the plumage mentioned by some authors may refer to iridescence, as seen in the straw-necked ibis. Subfossils of the Réunion ibis show that it was more robust, likely much heavier, and had a larger head than the African sacred and straw-necked ibises.

Archaeopteryx lithographica (Berlin specimen) Several non-avian dinosaurs had feathers on their limbs that would not have functioned for flight. One theory suggests that feathers originally evolved on dinosaurs due to their insulation properties; then, small dinosaur species which grew longer feathers may have found them helpful in gliding, leading to the evolution of proto-birds like Archaeopteryx and Microraptor zhaoianus. Another theory posits that the original adaptive advantage of early feathers was their pigmentation or iridescence, contributing to sexual preference in mate selection. Dinosaurs that had feathers or protofeathers include Pedopenna daohugouensis and Dilong paradoxus, a tyrannosauroid which is 60 to 70 million years older than Tyrannosaurus rex.

Corydoras panda has an off-white to pinkish-orange ground colour, and when observed under certain lighting conditions, a faint greenish iridescence is present upon the flanks and the operculum. The fins of the fish match the body in ground colour, upon close inspection being seen to be hyaline or translucent with coloured fin rays, with the dorsal fin being marked by a conspicuous black blotch that covers almost the entire fin area. The caudal peduncle is marked with a black band, this black band encircling the caudal peduncle from dorsal to ventral surface. The adipose fin, supported by a small fin spine, sometimes contains black pigmentation.

The octopus usually flashes its iridescent rings as a warning signal, each flash lasting around a third of a second. To test the theory if blue-ringed octopuses could produce their own blue iridescence, scientists bathed the octopus samples in a wide range of chemicals that were known to affect chromatophores and iridophores. It was found that none of the chemicals used affected the octopuses ability to produce its blue rings. It was also found that after examining the blue rings (specifically the iridophores) were seen to shift to the UV end of the spectrum which is a defining characteristic of multi-layer reflectors.

Electron micrograph of a fractured surface of nacre showing multiple thin layers Iridescence, as explained by Thomas Young in 1803, is created when extremely thin films reflect part of the light falling on them from their top surfaces. The rest of the light goes through the films, and a further part of it is reflected from their bottom surfaces. The two sets of reflected waves travel back upwards in the same direction. But since the bottom-reflected waves travelled a little further – controlled by the thickness and refractive index of the film, and the angle at which the light fell – the two sets of waves are out of phase.

The refractive index of Canadian material (as measured via sodium light, 589.3 nm) is as follows: α 1.522; β 1.672–1.673; γ 1.676–1.679; biaxial negative. Under ultraviolet light, ammolite may fluoresce a mustard yellow. An iridescent opal-like play of color is shown in fine specimens, mostly in shades of green and red; all the spectral colors are possible, however. The iridescence is due to the microstructure of the aragonite: unlike most other gems, whose colors come from light absorption, the iridescent color of ammolite comes from interference with the light that rebounds from stacked layers of thin platelets that make up the aragonite.

Avon River in Christchurch Morison's early work (from the time she finished art school) concentrated on 'severely formalist' paintings. After taking a break from exhibiting, in the mid 1980s Morison returned with a series of complex and ambitious works which became signatures in her career. Large multi-part works such as Vademecum (1986) and Golem (1987) are based on a system Morison created based on the number 10, referencing the Sefirothic Tree of Kabbalah and using ten 'logos' and ten key materials ('transparency', gold, silver, 'iridescence', lead, mercury or mercuric-oxide, clay, ash, blood, excrement), in various combinations. These systems continue to inform much of the artist's work.

The forewings are blackish with a broad band of bright blue iridescence from the base along the costa throughout, continued as a much attenuated fascia around the termen to the tornus. There is an oblong blue-hyaline blotch in the middle of the disc. The hindwings are blue-hyaline with a moderate blackish streak along the costa, joining a patch at the apex which occupies one-fourth of the wing, this meeting a very broad terminal band which occupies the lower half of the wing to the base, but includes ill-defined hyaline submedian and subdorsal streaks from the base to the tornus.Exotic Microlepidoptera.

Many ornamental freshwater aquarium fish, including the cardinal tetra and the discus (Symphysodon ssp.), are sourced from the Amazon River basin area. The Rio Negro region is the home of more than 100 different species of fish that are important to the pet fish trade. In fact several species, including cardinal tetras, show the adaptive trait of iridescence which may provide lower visibility in a blackwater environment. Project Piaba started with an ecological baseline study of the region which was conducted in 1989 by a group of researchers and students from the Universidade do Amazonas (UA) and the National Institute of Amazon Research (INPA).

A pendant made from modern dichroic glass Dichroic glass is glass which displays two different colors by undergoing a color change in certain lighting conditions. One dichroic material is a modern composite non-translucent glass that is produced by stacking layers of glass and micro-layers of metals or oxides which give the glass shifting colors depending on the angle of view, causing an array of colors to be displayed as an example of thin-film optics. The resulting glass is used for decorative purposes such as stained glass, jewelry and other forms of glass art. The commercial title of "dichroic" can also display three or more colors (trichroic or pleochroic) and even iridescence in some cases.

DARKSiDERS (also known as DS and DARKZER0) is a warez group releasing media formats under an application known as "0day" and ISOs under the tag of "-DARKZER0". The group have supposedly released since 2016 under DARKSiDERS (shortened as DS), although their first recorded release on Crackwatch was Iridescence on December 2018 under the name DARKZER0. DS released numerous other formats of pirated content including CD and Vinyl rips of Shows and Anime, MP3 and FLAC rips of music and music videos, eBook rips under the tag-dbOOk and various other Pornographic content under the tag -JAVSiDERS. Notoriety of DARKZER0 among anime and otaku culture has been quite positive among the releases of DARKZER0.

This is usually easy enough to do, but it can still be difficult for the inexperienced to differentiate the exact base colour between the many possibilities as there are often only subtle differences, as well as variations. The final (post doping) surface shades also vary according to the depth of base colour, as well as any special treatments and the type and amount of salts used. This last variable caused significant variation to occur, even between batches of what should have been essentially the same colour or colour-way. This happened most frequently in early production but to such an extent that collectors now differentiate between these items, describing the degree of iridescence showing.

The forewings are dark bronzy fuscous with the markings brilliant blue metallic, with green and purple iridescence. There is a spot on the base of the costa and an angulated transverse line at one-fifth, not reaching the dorsum, as well as a slightly curved entire transverse line slightly before the middle and two transverse linear marks in the disc beyond the middle, rather converging upwards, and a dot on the fold beneath them. An inwardly oblique mark is found from the costa at two-thirds and there is a large bright purple patch on the lower part of the termen, extending from the tornus to above the middle. The hindwings are dark fuscous.
|
|
The wingtip is most prominently marked; it is delimited by a blackish area of the leading and outer wing edge, connected by a metallic stripe which separates the forewing tip proper from the rest of the wing. The wingtip is white, with an ochre spot in the middle; at the inner edge of this spot, there is a small black dot. The hairy fringe of the forewings is grey along the trailing edge and white on the outer edge and wingtip; in the latter area, the hairs are tipped reddish grey. The hindwings are uniformly grey with a slight brassy iridescence; they, too, have a hairy fringe, which is grey all over in this case.

The wings and the square-tipped tail are black, with blue iridescence on the primary and secondary wing-coverts, and a striped patch formed by the light grey outer web of the tertiary remiges, with the grey scapulars sometimes dropping over the wings to form a grey shoulder patch. The uppertail coverts are likewise black, quite long, and have white tips that may have a signal function as they are sometimes prominently presented by the birds. The belly is white, and the throat has a patch of cherry red that varies in extent, in some birds reaching onto the breast. The feet and toenails are dull pink, and the iris is dark yellow.

There is a small bar on the tip of the lower lobe. The width of biggest lower caudal-fin lobe bar and/or the space between outermost bars is less than the diameter of the orbit. They doi not have any flank stripes and the tip of first dorsal-fin is dark, The barbels are white as is the belly while the flanks are rose-red darkening towards the back where there is some gold iridescence along the upper flanks and a dark saddle to the rear of the second dorsal fin. The body is uniformly brown, with a little dorsal darkening, with the bars and black first dorsal- fin tip still visible in preserved fish.

It was also found that the iridophores are nicely tucked into the modified skin folds, kind of like pouches, which could be contracted by the muscles that connect the center of each ring to the rim. When the muscles then relax, the muscles around the perimeter of the ring contract which in turn causes the pouch to open to expose the iridescent flash. The octopus can then expand the brown chromatophores on either side of its ring to enhance the contrast of its iridescence. After all of the testing was complete, it was determined that the muscle contracting mechanisms was key to how the blue-ringed octopus portrayed its iridescent signaling success.

The relatively long tail is made up of two long, white plumes with black spatulate tips with a violet iridescence, and the feathers beneath those are plain black. The drabber female has a dark brown to blackish head, lighter, dark brownish wings and back, dusky light brown underparts with heavy barring, and a similar tail to the male, but without a spatulate tip and a much more reduced amount of white on the upper tail. Subspecies helios is larger than splendidissima, male has a more blue than yellow-green crown, and larger spatulate tips on the longer two central feathers, and female has darker upperparts. They have dark-colored eyes, lead-grey legs and bill, and dark grey claws.

"Jackie Evancho, with a bell-like voice, elicits numerous ovations", The Washington Post, October 11, 2015 Reviewing one of Evancho's 2016 concerts, Steve Barnes similarly wrote for the Times Union that her voice is "an instrument of pristine beauty. It peals with the purity of bells and lofts tones that shimmer with celestial iridescence" but that her performance lacks "an apparent interpretive style or emotional connection to the material".Barnes, Steve. "Evancho Sparkles, Alas with Little Emotion", Times Union, November 27, 2016 A chapter in the 2016 book, Voicing Girlhood in Popular Music: Performance, Authority, Authenticity, by Dana Gorzelany-Mostak, Assistant Professor of Music at Georgia College, is devoted to analyzing Evancho's career and influence.

The cardinal tetra has bright red ventral parts and an iridescent blue line that runs horizontally down the length of its body. The characteristic iridescence of this and related fishes, such as the neon tetra, is a structural color, caused by refraction of light within guanine crystals that develop within special cells called iridocytes in the subcutaneous layer. The exact shade of blue seen will depend on the viewing angle of the aquarist relative to the fish - if the aquarist changes viewpoint so as to look at the fish more from below, the colour will change hue, becoming more deeply sapphire blue and even indigo. Change the viewpoint to one above the fishes, however, and the color becomes more greenish.

The iridescence on the paradise riflebird is blue, on the Victoria's riflebird blue-green, and on the magnificent and growling riflebirds green, blue, and purple. Males of the magnificent and growling riflebirds have more prominent grey-black underparts, black and yellow bands across their mid-breast and long thin curved plumes from the lower flanks that extend to the end of the tail in P. magnifica or just short in P. intercedens. Adult female riflebirds of the four species are also similar in appearance: all are largely brown above, have a prominent cream supercilium and whitish to buff with dark markings underneath. Female magnificent and growling riflebirds have thin blackish barring underneath, while paradise and Victoria's riflebirds have brown chevrons.

The two began working together to capture more videos of peacock courtship rituals to understand how the tail feathers vibrate, and how those vibrations are received by the females. They found that the train-rattling behavior only occurs when females are present and that, as the tail shakes, the eyespots on the tail appear not to move, leading them to conclude that the shaking behavior enhances the appearance of the eyespots of the tail. In previous work, Dakin found that the hue and iridescence of the tail's eyespots contribute to the mating success of the male. They also found that the tail feathers vibrate at their natural resonance frequency, producing sound waves that are within the audible range that females are able to hear.

Beyond this, a yellow- ochreous spot edged white on the costa and cut by a very oblique fine spatulate violet-metallic striga crosses half the wing and there is a streak of whitish suffusion running from the apex of the silvery costal patch to the tornus. An elongate dark fuscous spot is found on the dorsum beyond the middle, preceded and followed by spots of leaden suffusion and surrounded with violet iridescence. Three or four short black lines are located on the veins posteriorly, and a short white streak is found beneath the middle. A spot of bluish-silvery suffusion is found on the tornus and there is a small spot of blackish suffusion towards the apex, as well as a fine blackish line around the tornus.

As well as his contributions to The Church, Koppes has also released several solo albums, and albums with his group The Well (1989-1995), which largely occupied his time on hiatus from The Church. The Well featured former Church drummer Richard Ploog on drums, Anthony Smith (inaugural keyboardist for Flowers/Icehouse) and Jim Leone of The Celibate Rifles on bass. The Well played live and recorded songs that were released as an EP called Iridescence and later the fan favourite solo album Water Rites. There was still contact with Steve Kilbey, who asked Koppes to play guitar on some songs for albums he was producing, Australian artists Margot Smith's Adored and Lifetime, Stephen Cummings' Everything Breaks Your Heart, and Canadian Mae Moore's Full Circle.

Differs very slightly from the wet-season brood. In the male there is a small patch of white on the upperside of the forewing beyond the cell and on the upperside of the hindwing on the anterior portion of the disc; the extent of this patch varies on the forewing from a mere touch of white just beyond the cell to a large discal area of white which is diffuse with ill-defined margins. In the female the blue iridescence at the base of the wings on the upperside is in some specimens considerably restricted, in others entirely absent. On the underside in both sexes the ground colour is paler and in form and position the markings are much less prominent, though entirely like those of the wet-season brood.

Scales on a luna moth (Actias luna) Butterflies and moths - the order Lepidoptera (Greek "scale-winged") - have membranous wings covered in delicate, powdery scales, which are modified setae. Each scale consists of a series of tiny stacked platelets of organic material, and butterflies tend to have the scales broad and flattened, while moths tend to have the scales narrower and more hair like. Scales are usually pigmented, but some types of scales are metallic, or iridescent, without pigments; because the thickness of the platelets is on the same order as the wavelength of visible light the plates lead to structural coloration and iridescence through the physical phenomenon described as thin-film optics. The most common color produced in this fashion is blue, such as in the Morpho butterflies.

Thus, it has been known for many years that, due to repulsive Coulombic interactions, electrically charged macromolecules in an aqueous environment can exhibit long-range crystal-like correlations with interparticle separation distances, often being considerably greater than the individual particle diameter. In all of these cases in nature, the same brilliant iridescence (or play of colors) can be attributed to the diffraction and constructive interference of visible lightwaves that satisfy Bragg’s law, in a matter analogous to the scattering of X-rays in crystalline solids. The large number of experiments exploring the physics and chemistry of these so- called "colloidal crystals" has emerged as a result of the relatively simple methods that have evolved in the last 20 years for preparing synthetic monodisperse colloids (both polymer and mineral) and, through various mechanisms, implementing and preserving their long-range order formation.

As the TARDIS begins to shake violently, she says the Universe is being destroyed and there's only one person in all of existence who can stop it… Far away on the ocean planet of Orbis, the Doctor is occupying his time by repairing the wreck of a tiny spaceship. He's approached by Selta, a female of the jellyfish-like Keltan race, who tells him there's a storm approaching, and the distraction is enough for the drive belt to snap and whip the Doctor‘s fingers. Selta can’t tell whether he's angry as he doesn’t share the Keltans’ iridescence, but his repairs have come to an end unless he can find a replacement. He tells her that if they were on Earth he could use a pair of tights, but he's unlikely to find any here as there are no bipeds on this planet.

Adults have a glossy bluish-black iridescent head, neck, secondary flight feathers and tail; a coppery-brown crown; a bright white back and belly; bill black with a slightly concave upper edge; and bright red legs. The sexes are identical but the adult female has a yellow iris while the adult male has it brown. Juveniles younger than six months have a brownish iris; a distinctly smaller and straighter beak; a fluffy appearance; brown head, neck, upper back, wings and tail; a white belly; and dark legs. Juveniles older than six months have a mottled appearance especially on the head and neck where the iridescence is partly developed; dark-brown outer primaries; white inner primaries that forms a shoulder patch when the wings are closed; a heavy beak identical in size to adults but still straighter; and dark to pale-pink legs.

Eyeshine occurs in a wide variety of colors including white, blue, green, yellow, pink and red. However, since eyeshine is a type of iridescence, the color varies with the angle at which it is seen and the minerals which make up the reflective tapetum-lucidum crystals. White eyeshine occurs in many fish, especially walleye; blue eyeshine occurs in many mammals such as horses; green eyeshine occurs in mammals such as cats, dogs, and raccoons; and red eyeshine occurs in coyote, rodents, opossums and birds. A three-month-old black Labrador puppy with apparent eye shine Six year old Shih Tzu with eye shine made visible from a camera flash Although human eyes lack a tapetum lucidum, they still exhibit a weak reflection from the fundus, as can be seen in photography with the red- eye effect and with near-infrared eyeshine.

Wells's 2003 novel Iridescence was a runner-up in the fiction category of the Montana New Zealand Book Awards and a finalist in the 2005 Tasmania Pacific Fiction Prize. In the 2006 New Year Honours, Wells was appointed a Member of the New Zealand Order of Merit, for services to literature and film. He was awarded the Michael King Fellowship in 2011. In 2009 Wells was awarded a New Zealand non-fiction literary prize, convened by CLL (Copyright Licensing Ltd) to write a series of biographical essays on William Colenso, entitled The Hungry Heart: The Enquiring Mind. The book “will not be a conventional biography, but an essay series that bears directly on the episodes of heartbreak, loneliness, and sometimes horror that chequered the life of this gifted renaissance man – printer, writer, botanist, explorer, ex-missionary and intellectual maverick”.

Nobel Lecture: The Isolation and Properties of Crystalline TMV (1946) It has been known for many years that, due to repulsive Coulombic interactions, electrically charged macromolecules in an aqueous environment can exhibit long-range crystal-like correlations with interparticle separation distances often being considerably greater than the individual particle diameter. In all of the cases in nature, the same iridescence is caused by the diffraction and constructive interference of visible lightwaves which falls under Bragg’s law. Because of the rarity and pathological properties, neither opal nor any of the organic viruses have been very popular in scientific laboratories. The number of experiments exploring the physics and chemistry of these “colloidal crystals” has emerged as a result of the simple methods which have evolved in 20 years for preparing synthetic monodisperse colloids, both polymer and mineral, and, through various mechanisms, implementing and preserving their long-range order formation.

Illustration of a female A. rothschildi. This little-known astrapia is a medium-sized bird-of-paradise species, excluding the tail. The males reach up to around 69 cm (27 in) long and weighs up to 205g, including the tail, while the smaller female is around 47 cm (18.5 in) long and weighs slightly less at 200g. The males' head to breast are black with a velvety-blue iridescence, bordered by a characteristic iridescent, coppery-orange gorget-band; the hindneck is an elongated erectile cape with iridescent blue-green plate-like feathers, tipped pinkish-violet (cape may appear fully violet in some views.); upperparts, including wings, are black with a slight bronze-green sheen, underparts are a deep oily green, with larger, scale-like feathers down the sides a shiny lime-green; the impressively long tail feathers are purplish- black with a bluish sheen.

Butterfly wing at different magnifications reveals microstructured chitin acting as a diffraction grating A number of fixed structures can create structural colours, by mechanisms including diffraction gratings, selective mirrors, photonic crystals, crystal fibres and deformed matrices. Structures can be far more elaborate than a single thin film: films can be stacked up to give strong iridescence, to combine two colours, or to balance out the inevitable change of colour with angle to give a more diffuse, less iridescent effect. Each mechanism offers a specific solution to the problem of creating a bright colour or combination of colours visible from different directions. Drawing of 'firtree' micro-structures in Morpho butterfly wing scale A diffraction grating constructed of layers of chitin and air gives rise to the iridescent colours of various butterfly wing scales as well as to the tail feathers of birds such as the peacock.

The first music video from the album for "Bruise" was directed by Brockhampton's Kevin Abstract. That same year, he also collaborated with rapper Tyler, the Creator on his EP Music Inspired by Illumination & Dr. Seuss' The Grinch and producer Benny Blanco on his album Friends Keep Secrets. Additionally, he performed with Brockhampton on The Tonight Show Starring Jimmy Fallon, alongside Jazmine Sullivan and serpentwithfeet, singing backing vocals on an early version of the song "Tonya" which later appeared on their album Iridescence. His backing vocals were later cut from the final version of the song.Beatty performing in March 2019Starting in January 2019, Beatty embarked on a short tour in support of his album Boy in Jeans, first with shows in Los Angeles and Brooklyn and then continuing in March with a West Coast tour with shows in Seattle, Portland, San Francisco, San Diego, and Los Angeles.

The forewings are pale grey suffusedly irrorated (sprinkled) with white, with a few scattered black scales and a black dot on the base of the costa, as well as slight strigulae before and beyond one- fourth. There is a semi-oval blackish spot on the middle of the costa and an oblique blackish spot in the disc somewhat before this, resting on a streak of grey suffusion mixed with blackish along the fold to near the extremity, connected with the dorsum by suffused spots before the middle and at four- fifths. There is an elongate black mark in the disc at three-fourths and a small grey spot on the costa above this, as well as a streak of grey suffusion along the termen, mixed with blackish on the tornus. The hindwings are grey, anteriorly thinly scaled and subhyaline (almost glass like) with violet-blue iridescence.

The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data are stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive that spins the disc at speeds of about 200 to 4,000 RPM or more, depending on the drive type, disc format, and the distance of the read head from the center of the disc (outer tracks are read at a higher data speed due to higher linear velocities at the same angular velocities). Most optical discs exhibit a characteristic iridescence as a result of the diffraction grating formed by its grooves.

" In describing Colon's work in the historical context of California Minimalism and Light & Space movements, critic Dr. Suzanne Hudson states, "Colon's 'Glo-Pods,' 2013—, irregularly shaped wall mounted acrylic orbs, recall the languid organicism of Craig Kauffman's candy-colored bubbles; their intimation of light emanating from within the impossibly smooth contours additionally channels Helen Pashgian's illuminated monoliths. Unlike Pashgian's plinths, or Doug Wheeler's neon-backlit canvases, Colon's scarab-like objects achieve their iridescence via the play of natural light, yet the sculptures appear to change color as one moves around them, as if lit by multihued bulbs.Perhaps more to the broader point, Colon's labors are very much her own…" Art critic Mat Gleason explained: "Rather than have some technological trick embedded into the art, [Colon] has made objects that are altered by the world around them yet never stop being themselves. This artist has thus delivered a meditation on the flexibility of the feminine as antidote to the rigidity of the masculine.

A colloidal crystal is a highly ordered array of particles that forms over a long range (from a few millimeters to one centimeter in length); colloidal crystals have appearance and properties roughly analogous to their atomic or molecular counterparts. It has been known for many years that, due to repulsive Coulombic interactions, electrically charged macromolecules in an aqueous environment can exhibit long-range crystal-like correlations, with interparticle separation distances often being considerably greater than the individual particle diameter. Periodic arrays of spherical particles give rise to interstitial voids (the spaces between the particles), which act as a natural diffraction grating for visible light waves, when the interstitial spacing is of the same order of magnitude as the incident lightwave. In these cases in nature, brilliant iridescence (or play of colours) is attributed to the diffraction and constructive interference of visible lightwaves according to Bragg's law, in a matter analogous to the scattering of X-rays in crystalline solid.

The forewings are dark grey with a fine whitish median longitudinal line from the base to the mediodorsal blotch, sometimes merged in a general obscure whitish suffusion of this area, sometimes a yellow or whitish streak beneath the costa towards the base, and a faint violet streak beneath this. There is an oblique dark-edged yellow-ochreous striga from the middle of the costa, and a fine violet striga, white on the costa, on each side of it. A dark fuscous fasciate curved oblique mediodorsal blotch reaches three-fourths across the wing, parallel sided, edged with whitish ochreous, the apex pointed posteriorly. There is another incurved whitish-ochreous streak beyond the upper portion of this, and some leaden iridescence towards the dorsum and an irregular obscure leaden transverse line is found at three-fourths, edged with whitish ochreous towards the costa and crossed by an oblique whitish-ochreous mark in the disc.

Hindwing: crossed by six or seven irregular, more or less broken, sublunular, white striations; terminal markings similar to those on the forewing; interspace 1 with a minute, interspace 2 with a much larger round jet-black spot, both spots crowned inwardly with ochraceous orange and touched outwardly with glittering metallic blue scales. Antennae black, the shafts obscurely speckled with white on the sides; head, thorax and abdomen purplish brown; beneath: the palpi fringed with black hairs, the thorax bluish white, abdomen white. Female upperside, forewing: costa above the cell, apex very broadly and a terminal edging that occupies about one-third of the length of the wing jet- black, this colour on the costa widened outwards; the remainder of the wing white shaded with dusky greyish which in certain lights has a beautiful metallic blue iridescence; on the inner side of the terminal edging is a transverse, very ill-defined, diffuse dusky band, and enclosed between it and the black edging three somewhat prominent spots of the white ground colour.

While biologists would regard this object as a kind of pearl, gemologists regard it as a non-nacreous pearl, lacking the iridescence of the pearls that come from saltwater pearl oysters and freshwater pearl mussels. Because of its great size, a giant clam can create a very large pearl, but not an iridescent, gemlike one. The Gemological Institute of America (GIA) and CIBJO now simply use the term "pearl" (or, where appropriate, the more descriptive term "non-nacreous pearl") when referring to such items, rather than the term "calcareous concretion"The Pearl Book , International Jewellery Confederation.GIA Gems & Gemology magazine news archive, December 3, 2008 (archived from the original on 2008-12-04) and, under U.S. Federal Trade Commission rules, various mollusk pearls may be referred to as "pearls" without qualification.Guides for the Jewelry, Precious Metals, and Pewter Industries Gemologist Michael Steenrod in Colorado Springs has appraised the pearl at $60,000,000 (1982) and $93,000,000 (2007). Another 1982 appraisal, by Lee Sparrow who owned a gem laboratory and appraisal business in the Phelan Building in San Francisco, put the pearl at $42,000,000.

By late 1944, Gordon was resident in New York, a regular at bebop jam sessions, and a featured soloist in the Billy Eckstine big band (If That's The Way You Feel, I Want To Talk About You, Blowin' the Blues Away, Opus X, I'll Wait And Pray, The Real Thing Happened To Me, Lonesome Lover Blues, I Love the Rhythm in a Riff). During early 1945 he was featured on recordings by Dizzy Gillespie (Blue 'n' Boogie, Groovin' High) and Sir Charles Thompson (Takin' Off, If I Had You, 20th Century Blues, The Street Beat). In late 1945 he was recording under his own name for the Savoy label. His Savoy recordings during 1945-46 included Blow Mr. Dexter, Dexter's Deck, Dexter's Minor Mad, Long Tall Dexter, Dexter Rides Again, I Can't Escape From You, and Dexter Digs In. He returned to Los Angeles in late 1946 and in 1947 was leading sessions for Ross Russell's Dial label (Mischievous Lady, Lullaby in Rhythm, The Chase, Iridescence, It's the Talk of the Town, Bikini, A Ghost of a Chance, Sweet and Lovely).
