Complementary

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

#fa0060

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.

#fa00dd

#fa1d00

Triadic

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

#9a00fa

#fa9a00

Analogous

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

#00fa1d

#00ddfa
