What is color harmony?

Color harmony describes how hues relate on the color wheel to create balance and contrast.

Common harmony models:
- Complementary: Opposite colors for strong contrast (brand highlights, call-to-action buttons)
- Analogous: Neighboring colors for calm, blended gradients (dashboards, infographics)
- Triadic: Three equidistant colors for lively but balanced palettes (app themes, marketing assets)
- Tetradic: Double complementary pairs for complex palettes with primary and accent roles
- Split complementary: Alternate to complementary that reduces harsh contrast while staying punchy
- Monochromatic: Tints and shades of one hue for consistent UI states and accessibility
