Primary colors are ones that are "original" for lack of a better word!. You can't mix two colors to create them!. There are three!.!.!. Red, Yellow, and Blue!.

Secondary colors are created by mixing two primary colors!. Red and Yellow create Orange!. Yellow and Blue make Green (as noted by the famous zip-loc commercial), and Blue and Red make Purple!.Www@QuestionHome@Com
