color wheel
A circle shape that is divided equally in to 12 sections, with each section displaying a different color according to its pigment value. As all colors are created from the three primary colors (red, green and blue), the primary colors are shown forming a triangle within the color wheel. The color wheel shows the relationship between the primary colors, secondary colors, and complementary colors.
