Summary

Complementary colors are important in painting, design, and color science because they can neutralize one another or create striking contrast. This lesson introduces the idea and explains why complementary pairs vary between color systems.

Complementary colors, sometimes called opposite colors, are colors that can cancel one another when combined or mixed, reducing their chroma and producing a neutral such as gray, white, or black. The precise result depends on whether the colors are light or pigments and on the color model being used.

What are complementary colors?
They are color pairs that can cancel or neutralize one another when combined, reducing chroma. When placed beside each other, vivid complements create strong contrast.
What is chroma?
Chroma is the strength or saturation of a color. High-chroma colors appear vivid; adding a complement tends to make them less vivid.
What is an RGB complementary pair?
Red and cyan are an RGB complementary pair. The other common RGB pairs are green–magenta and blue–yellow.
What are the traditional RYB complementary pairs?
Red–green, blue–orange, and yellow–purple are the traditional pairs used in the RYB color wheel.
Why do complementary pairs differ between systems?
Color models use different rules and primaries, and everyday color terms such as blue can cover a wide range of hues.
