Colour Harmony Reference

Complementary — Two hues 180° apart. Maximum contrast. Great for CTAs and accents that need to pop against a brand colour.

Triadic — Three hues 120° apart. Vibrant and playful with good visual balance. Reduce saturation on two of the three for elegant results.

Analogous — Five hues 30° apart. Found in nature — sunsets, forests. Calm, cohesive, never jarring. Ideal for backgrounds and long-form reading.

Split-Complementary — Seed plus two hues flanking its complement (150° and 210°). Retains contrast but is softer and easier to work with than pure complementary.

Tip: Pick a seed colour that matches your brand, then use an analogous palette for backgrounds and a complementary or split-complementary accent for interactive elements.
