The color wheel is an invaluable tool that teaches us how hues relate to each other and how they can be combined to create harmonious, cohesive color schemes. Featuring an illustrative organization of colors around a circle, it has become a favorite of designers, artists and do-it-yourselfers looking to revitalize their living spaces. The wheel makes color relationships easy to see by dividing the spectrum into 12 basic hues: three primary colors, three secondaries, and six tertiaries.

• Primary colors are red, blue, and yellow. These colors are pure, meaning you can’t create them from other colors. At the same time, they are the three basic colors from which all other colors are created.
