A color wheel is disk-shaped and divided equally into 12 sections, each displaying a different color according to its "pigment" values.

All colors arise from the three primary colors: red, blue and yellow. These colors are primary because you cannot make them by mixing other colors together. They are represented on thecolor wheel at equidistant positions, forming a triangle.

Mixing equal values of any two primary colors together creates the secondary colors of violet, orange and green. Since violet is a combination of equal amounts of blue and red, it lies halfway between those two colors on the color wheel. Orange lies halfway between red and yellow, and green between yellow and blue. The secondary colors form another triangle.

To fill the last 6 spaces on the color wheel, the tertiary colors are represented. Adding equal amounts of one primary and one secondary color, or the colors to either side on the wheel, results in the tertiary colors between. Flanked by red and orange you will see red-orange, between orange and yellow, yellow-orange, followed by yellow-green, blue-green, blue-violet, and red-violet.
