The ellipses (green, cyan, red) are hypotrochoids of the Tusi couple. A property of the Tusi couple is that points on the inner circle that are not on the circumference trace ellipses. These ellipses, and the straight line traced by the classic Tusi couple, are special cases of hypotrochoids.

It is this version that is described here. The game uses colourful double- sided triangular playing tiles called trangs. The trangs use all the permutations of red, yellow, green, cyan and magenta to give 35 unique trangs, plus one all-white 'joker'. Each trang is marked with a number that is the basic scoring value of that tile.

A Casio digital LCD watch with an electroluminescent backlight. Powder phosphor-based electroluminescent panels are frequently used as backlights for liquid crystal displays. They readily provide gentle, even illumination for the entire display while consuming relatively little electric power. This makes them convenient for battery-operated devices such as pagers, wristwatches, and computer-controlled thermostats, and their gentle green-cyan glow is common in the technological world.

Many different methods of testing have been employed to view the effects of chromostereopsis on depth perception in humans. Technological progress has allowed for accurate, efficient, and more conclusive testing, in relation to the past, where individuals would merely observe the occurrence. In one method, twenty-five control subjects were tested using color-based depth effects through the use of five different colored pairs of squares. The different colors were blue, red, green, cyan and yellow.

This method is similar in principle to field-sequential color system by CBS and other sequential color methods such as used in Digital Light Processing (DLP). upright=0.3 The demonstration on the right mixes cyan and green-cyan statically (top) and by rapidly alternating the colors. (bottom) The size of the thumbnail has been reduced to reduce the flicker people may experience in their peripheral vision while reading the article. In a monitor that uses FRC the alternating colors would be more similar, reducing the flicker effect.

Each screen (called a floor), has a set of dice of different colours (blue, red, magenta, green, cyan and white). The player shuffles the dice around the play area, using a frame surrounding 4 of the dice at a time. Dice within this frame can be rotated 90° around a central axis, with the ultimate aim of lining up the dice in the correct colour before the time and move limit expired. Later levels introduce a third dimension of the dice scattered between 2 and 5 floors.

Early color cameras used the obvious technique of using separate red, green and blue image tubes in conjunction with a color separator, a technique still in use with 3CCD solid state cameras today. It was also possible to construct a color camera that used a single image tube. One technique has already been described (Trinicon above). A more common technique and a simpler one from the tube construction standpoint was to overlay the photosensitive target with a color striped filter having a fine pattern of vertical stripes of green, cyan and clear filters (i.e.

On 28 December 1918, Kelley announced that Prizma would release a color film (usually a short) every week, a film which would be projectable on any standard projector. Kelley's idea was two years in the making, but was a valid one which became the springboard for all future color systems to follow — two films were filmed simultaneously with a camera of his own design. One strip was sensitive to red-orange, the other to blue-green (cyan). Both negatives were processed and printed on duplitized film, and then each emulsion was toned its complementary color, red or blue.

Legend has it that two demons were jailed in the Calabash Mountain, one a Scorpion spirit and the other a Snake spirit. One day, a pangolin happens to drill a hole on the slope and the two spirits escape from the cave, causing grave harm to the nearby residents. The pangolin hurries to an old man and says that only by growing calabashes in seven colors can they annihilate the spirits. So the old man spares no time in growing seven calabashes, each a different color of the rainbow: red, orange, yellow, green, cyan, blue, and purple.

The three great races according to Meyers Konversations-Lexikon of 1885-90. The subtypes of the Mongoloid race are shown in yellow and orange tones, those of the Caucasoid race in light and medium grayish spring green-cyan tones and those of the Negroid race in brown tones. Dravidians and Sinhalese are in olive green and their classification is described as uncertain. The Mongoloid race sees the widest geographic distribution, including all of the Americas, North Asia, East Asia, and Southeast Asia, the entire inhabited Arctic while they form most of Central Asia and the Pacific Islands.

Later scientists conclude that Newton named the colors differently from current usage. According to Gary Waldman, "A careful reading of Newton's work indicates that the color he called indigo, we would normally call blue; his blue is then what we would name blue-green, cyan or light blue." If this is true, Newton's seven spectral colors would have been: Red: Orange: Yellow: Green: Blue: Indigo: Violet: The human eye does not readily differentiate hues in the wavelengths between what we today call blue and violet. If this is where Newton meant indigo to lie, most individuals would have difficulty distinguishing indigo from its neighbors.

The JR-200 did not use Microsoft BASIC, but its own dialect, one that was designed to be mostly compatible with Microsoft BASIC. JR-BASIC was a greatly extended Basic, with, (for example) graphical commands such as COLOR, (which selected character color, background color and display mode) and PLOT which permitted direct addressing of the low resolution graphics mode (64×48, using text semigraphics characters, which represented pixel blocks that used one-quarter of each character). Eight colors were available for the background and foreground use: blue, red, magenta, green, cyan, yellow, white and black. By re-programming a part of the character-set a limited high resolution graphics mode was achievable with a resolution of 256×192.

The function which is identically zero on U can be approximated by ζ: we can first pick the "nearby" function (which is holomorphic and doesn't have zeros) and find a vertical displacement such that ζ approximates g to accuracy ε/2, and therefore f to accuracy ε. The accompanying figure shows the zeta function on a representative part of the relevant strip. The color of the point s encodes the value ζ(s) as follows: the hue represents the argument of ζ(s), with red denoting positive real values, and then counterclockwise through yellow, green cyan, blue and purple. Strong colors denote values close to 0 (black = 0), weak colors denote values far away from 0 (white = ∞).

HSL and HSV are both cylindrical geometries (), with hue, their angular dimension, starting at the red primary at 0°, passing through the green primary at 120° and the blue primary at 240°, and then wrapping back to red at 360°. In each geometry, the central vertical axis comprises the neutral, achromatic, or gray colors ranging, from top to bottom, white at lightness 1 (value 1) to black at lightness 0 (value 0). In both geometries, the additive primary and secondary colors—red, yellow, green, cyan, blue and magenta—and linear mixtures between adjacent pairs of them, sometimes called pure colors, are arranged around the outside edge of the cylinder with saturation 1. These saturated colors have lightness 0.5 in HSL, while in HSV they have value 1.

The board contains 16 rows and 16 columns, for a total of 256 squares, and can also be described as consisting of 8 rings. The first ring consists of the squares on the outer edge of the board (ranks 1 and 16 and files a and p), with subsequent rings moving inward. The eighth ring consists of the center four squares at h8, h9, i8, and i9. The board contains two squares of each color represented in the game: Achromatic Colors: White, Ash, Slate, and Black Chromatic Colors: Pink, Red, Orange, Yellow, Green, Cyan, Navy, and Violet All colored squares are located near the center of the board (between ranks 5 through 12 and files e through l), but only the achromatic colors are located within the middle 4 × 4 region (between ranks 7 through 10 and files g through j).

Cells made from multiple materials layers can have multiple bandgaps and will therefore respond to multiple light wavelengths, capturing and converting some of the energy that would otherwise be lost to relaxation as described above. For instance, if one had a cell with two bandgaps in it, one tuned to red light and the other to green, then the extra energy in green, cyan and blue light would be lost only to the bandgap of the green-sensitive material, while the energy of the red, yellow and orange would be lost only to the bandgap of the red-sensitive material. Following analysis similar to those performed for single-bandgap devices, it can be demonstrated that the perfect bandgaps for a two-gap device are at 0.77 eV and 1.70 eV. Conveniently, light of a particular wavelength does not interact strongly with materials that are of bigger bandgap.

For example, consider an Stripe Panel: WWWWWWWWWWWWWWWWWW = red is WWWWWWWWWWWWWWWWWW = green perceived WWWWWWWWWWWWWWWWWW where = blue as WWWWWWWWWWWWWWWWWW W = white WWWWWWWWWWWWWWWWWW Shown below is an example of black and white lines at the Nyquist limit, but at a slanting angle, taking advantage of subpixel rendering to use a different phase each row: _________ WWW___WWW___WWW___ = red _________ is _WWW___WWW___WWW__ = green _________ perceived __WWW___WWW___WWW_ where = blue _________ as ___WWW___WWW___WWW _ = black __________ ____WWW___WWW___WW W = white Shown below is an example of chromatic aliasing when the traditional whole pixel Nyquist limit is exceeded: ________ ________ = red = yellow ________ is ________ = green = cyan ________ perceived ________ where = blue = magenta ________ as ________ _ = black ________ ________ This case shows the result of attempting to place vertical black and white lines at four subpixels per cycle on the Stripe architecture. One can visually see that the lines, instead of being white, are colored. Starting from the left, the first line is red combined with green to produce a yellow-colored line. The second line is green combined with blue to produce a pastel cyan-colored line.

This diagram shows three examples of color halftoning with CMYK separations, as well as the combined halftone pattern and how the human eye would observe the combined halftone pattern from a sufficient distance. With CMYK printing, halftoning (also called screening) allows for less than full saturation of the primary colors; tiny dots of each primary color are printed in a pattern small enough that humans perceive a solid color. Magenta printed with a 20% halftone, for example, produces a pink color, because the eye perceives the tiny magenta dots on the large white paper as lighter and less saturated than the color of pure magenta ink. Without halftoning, the three primary process colors could be printed only as solid blocks of color, and therefore could produce only seven colors: the three primaries themselves, plus three secondary colors produced by layering two of the primaries: cyan and yellow produce green, cyan and magenta produce blue, yellow and magenta produce red (these subtractive secondary colors correspond roughly to the additive primary colors), plus layering all three of them resulting in black.
