Colors of The Color Wheel
A typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet. The tertiary colors are red–orange, red–violet, yellow–orange, yellow–green, blue–violet and blue–green.
A color wheel based on RGB (red, green, blue) or RGV (red, green, violet) additive primaries has cyan, magenta, and yellow secondaries (cyan was previously known as cyan blue). Alternatively, the same arrangement of colors around a circle can be described as based on cyan, magenta, and yellow subtractive primaries, with red, green, and blue (or violet) being secondaries.
Most color wheels are based on three primary colors, three secondary colors, and the six intermediates formed by mixing a primary with a secondary, known as tertiary colors, for a total of 12 main divisions; some add more intermediates, for 24 named colors. Other color wheels, however, are based on the four opponent colors, and may have four or eight main colors.
Goethe's Theory of Colours provided the first systematic study of the physiological effects of color (1810). His observations on the effect of opposed colors led him to a symmetric arrangement of his color wheel, "for the colours diametrically opposed to each other… are those that reciprocally evoke each other in the eye." (Goethe, Theory of Colours, 1810 ). In this, he anticipated Ewald Hering's opponent color theory (1872).

Famous quotes containing the words colors, color and/or wheel:
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
“When a bachelor of philosophy from the Antilles refuses to apply for certification as a teacher on the grounds of his color I say that philosophy has never saved anyone. When someone else strives and strains to prove to me that black men are as intelligent as white men I say that intelligence has never saved anyone: and that is true, for, if philosophy and intelligence are invoked to proclaim the equality of men, they have also been employed to justify the extermination of men.”
—Frantz Fanon (1925–1961)
“Let go thy hold when a great wheel runs down a hill lest it break thy neck with following; but the great one that goes upward, let him draw thee after.”
—William Shakespeare (1564–1616)
