Colour harmonies
Colour harmonies are fixed positions on the colour wheel. Complementary: opposite hues (180° apart). Analogous: neighbours (±30°). Triadic: three hues 120° apart. Split-complementary: the base plus the two neighbours of its complement. Tetradic: two complementary pairs. Monochromatic: one hue in several lightness steps.
