With art supplies, there are three primary colors: red, yellow, and blue. You can mix these colors together to make all the other colors but no colors can be mixed together to make red, yellow, and blue. Look for the primary colors that separate out of the marker color! You can remember the colors of the rainbow with the acronym ROY G BIV, where each letter stands for the name of a color.
