Glossary

Saturation The strength or intensity of a color based on the degree to which it lacks its complementary color. For example, a strongly saturated blue would have little or no yellow (its complementary color) in it. A red with little saturation would have a lot of cyan (its complementary color) mixed in, and as a result, would look muddy or dark.
