basic color theory definition

Basic color theory says that the three primary colors - red, yellow and blue - cannot be made from other colors.  Instead, all three colors are mixed in various ways to create all other colors.  Secondary colors - green, orange and purple - are made from mixing the primary colors together.  And tertiary colors - yellow/orange, yellow/green, red/orange, blue/green, and blue/violet are made from mixing the secondary colors.
