Combinations of color are called Color Harmonies. Also known as color schemes, they are a way of choosing colors in a way to create a certain effect. Color harmonies are all based on the color wheel. The list below covers the basic color harmonies that are used in art and design. This is by no means exhaustive, and there are hundreds of other color schemes, sometimes called palettes, that can be used. However, most other color schemes are derived from these basic color harmonies.
