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).

“... ideals, standards, aspirations,—those are chameleon words, and take color from their speakers,—often false tints. A scholarly man of my acquaintance once told me that he traveled a thousand miles into the desert to get away from the word uplift, and it was the first word he heard after he reached his destination.”
—Carolyn Wells (1862–1942)
“A wheel that can be turned though nothing else moves with it, is not a part of the mechanism.”
