It suppresses primary pigment made in petals, leaving areas where the white or yellow underlying color shows.

Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs yellow and blue wavelengths of light while reflecting green. It is the presence and relative abundance of chlorophyll that gives plants their green color. Green algae and plants possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a.

Several unique chemicals are produced by Mycena haematopus. The primary pigment is haematopodin B, which is so chemically sensitive (breaking down upon exposure to air and light) that its more stable breakdown product, haematopodin, was known before its eventual discovery and characterization in 2008. A chemical synthesis for haematopodin was reported in 1996. Haematopodins are the first pyrroloquinoline alkaloids discovered in fungi; pyrroloquinolines combine the structures of pyrrole and quinoline, both heterocyclic aromatic organic compounds.

All biological pigments selectively absorb certain wavelengths of light while reflecting others. The light that is absorbed may be used by the plant to power chemical reactions, while the reflected wavelengths of light determine the color the pigment appears to the eye. Chlorophyll is the primary pigment in plants; it is a porphyrin that absorbs red and blue wavelengths of light while reflecting green. It is the presence and relative abundance of chlorophyll that gives plants their green color.

Cyan, magenta and yellow are the three subtractive primary colors used in printing. In color printing, the color called process magenta or pigment magenta is one of the three primary pigment colors which, along with yellow and cyan, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips. Process magenta is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB.

Cyan, magenta, and yellow are the three subtractive primary colors used in printing. In color printing, the shade of cyan called process cyan or pigment cyan is one of the three primary pigment colors which, along with yellow and magenta, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips. Process cyan is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB.

In colour printing, the colour called process magenta, pigment magenta, or printer's magenta is one of the three primary pigment colours which, along with yellow and cyan, constitute the three subtractive primary colours of pigment. (The secondary colours of pigment are blue, green, and red.) As such, the hue magenta is the complement of green: magenta pigments absorb green light; thus magenta and green are opposite colours. The CMYK printing process was invented in the 1890s, when newspapers began to publish colour comic strips. Process magenta is not an RGB colour, and there is no fixed conversion from CMYK primaries to RGB.

The portion of the R cells at the central axis of the ommatidium collectively form a light guide, a transparent tube, called the rhabdom. Although composed of over 16,000 cells, the Drosophila compound eye is a simple repetitive pattern of 700 to 750 of ommatidia, initiated in the larval eye imaginal disc. Each ommatidium consists of 14 neighboring cells: 8 photoreceptor neurons in the core, 4 non-neuronal cone cells and 2 primary pigment cells. A hexagonal lattice of pigment cells insulates the ommatidial core from neighboring ommatidia to optimize coverage of the visual field, which therefore affects the acuity of Drosophila vision.
