What Are the Formulas for Mixing Colors?

There are no exact formulas for mixing colors, but there are several rules to remember when mixing colors. The basics of color lie in the color wheel. Primary colors, which are pure red, yellow and blue, are the root of every color mixture. Secondary and tertiary colors are created from these colors.

The mixture of any two primary colors always creates a secondary color. The secondary colors are orange, violet or purple, and green. Mixing red and yellow makes orange. Mixing red and blue makes purple. Mixing blue and yellow makes green. Primary and secondary colors make the standard color wheel. Notice these colors are also all the colors of the rainbow and are situated in the wheel in the same order: red, orange, yellow, green, blue and purple.

Tertiary colors arise when a primary color is mixed with the secondary color that lies beside it. Yellow and orange make yellow-orange. Red and orange make red-orange. Red and violet make red-violet. Blue and violet make blue-violet. Blue and green make blue-green. Yellow and green make yellow-green. Altogether, primary, secondary and tertiary colors create 12 total colors on the color wheel. Each of these colors has various hues, tints, shades and tones that create even more colors.
