Subtractive Color Wheel

As the title tells you, this is a subtractive color wheel, which means that it represents the colors produced by mixing pigments which reflect certain colors of light. The three primary colors, those which we cannot attain by mixing other colors are Red, Yellow and Blue. When we mix two of these evenly, we wind up with the secondary colors: Violet, Orange and Green. Mixing a primary color and a secondary color creates a terciary color (the six visable on the wheel that are left.)

Round the outside of the wheel the shapes you see are pure colors. In the inner rings you see lower intensity variations: from the outside in you see tints, tones, and shades. A tint is a color mixed with white, a tone is acolor mixed with grey, and a shade is a color mixed with black.
