Complementary

The opposite hue, 180° away — the strongest contrast, best kept to one accent per screen.

#b33c7e

Split-complementary

The two neighbors of the complement, at 150° and 210° — most of the contrast with less tension, and two accents instead of one.

#ac3cb3

#b33c43

Triadic

Two hues at 120° and 240° — three evenly spaced signals, the scheme charts and category colors want.

#713cb3

#b3713c

Analogous

The neighbors at −30° and +30° — calm and cohesive, with emphasis coming from weight and size rather than hue.

#43b33c

#3cb3ac
