Tetradic colors

Four colors made of two complementary pairs, spaced in a rectangle or square on the wheel.

Also called tetradic, square color scheme, double complementary

A tetradic (or square) scheme uses two pairs of complementary colors. It offers the most variety of any harmony.

With four strong hues it is easy to overdo; pick one dominant color and keep the others in smaller amounts.
