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 of, colors, color and/or wheel:
“Nature always wears the colors of the spirit. To a man laboring under calamity, the heat of his own fire hath sadness in it.”
—Ralph Waldo Emerson (1803–1882)
“We may say that feelings have two kinds of intensity. One is the intensity of the feeling itself, by which loud sounds are distinguished from faint ones, luminous colors from dark ones, highly chromatic colors from almost neutral tints, etc. The other is the intensity of consciousness that lays hold of the feeling, which makes the ticking of a watch actually heard infinitely more vivid than a cannon shot remembered to have been heard a few minutes ago.”
—Charles Sanders Peirce (1839–1914)
“Rain falls into the open eyes of the dead
Again again with its pointless sound
When the moon finds them they are the color of everything”
—William Stanley Merwin (b. 1927)
“But if you know that you are a man too, and that even such are those that rule, learn this first of all: that all human affairs are a wheel which, as it turns, does not allow the same men always to be fortunate.”
—Herodotus (c. 484–424 B.C.)
