Primary colors of the CMY color model: cyan, magenta, and yellow, mixed to form secondary colors red, green, and blue. The RGB color model is an additive mixing model, used to estimate the mixing of colored light, with primary colors red, green, and blue. The secondary colors are yellow, cyan and magenta as demonstrated here:
Red, yellow, and blue are the primary colors of the RYB color "wheel". The secondary colors, violet (or purple), orange, and green (VOG) make up another triad, conceptually formed by mixing equal amounts of red and blue, red and yellow, and blue and yellow, respectively. Classification of pigment colors
Some of the most well-known color models and color spaces are RGB, CMYK, HSL/HSV, CIE Lab, and YCbCr/YUV. Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality. Names of color regions in different cultures can have different, sometimes overlapping areas.
The various colors are made by the combination of the different layers of the chromatophores. These cells are usually located beneath the skin or scale the animals. There are two categories of colors generated by the cell – biochromes and schematochromes. Biochromes are colors chemically formed microscopic, natural pigments.
Color theory dates back at least as far as Aristotle's treatise On Colors. A formalization of "color theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color (Opticks, 1704) and the nature of primary colors. By the end of the 19th century, a schism had formed between traditional color theory ...
The reviewer finds the closing chapters on "colors used in courtship" the most interesting of the book, since zoologists disagreed widely on the subject, and notes that Poulton sided with Darwin and against Wallace "who denies that the so-called secondary sexual characters" can "owe their origin to sexual selection".

The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
