Since each monitor shows colors differently I labeled each section. I suggest you buy a real one at your local art supply store or you can order one on the internet from The Color Wheel Company . This lesson is about the color wheel. It is a useful tool for organizing colors. The Color Wheel describes the relationships between colors.
Primary colors are hues which can be mixed to create all other colors.
Primary Colors are basic and cannot be mixed from other elements. They are to color what prime numbers are to mathematics. One can mix two primaries to get a Secondary Color. You will notice that each Secondary Color on the Color Wheel is bounded by two primaries. These are the components that one would mix to get that Secondary Color.
