Frequently asked questions
What are the main colour harmony types?
Complementary is two hues 180 degrees apart; analogous is neighbours within about 30 degrees; triadic is three hues 120 degrees apart; tetradic (square) is four at 90 degrees; and monochromatic varies only saturation and lightness of a single hue.
Which harmony should I choose for a website?
Analogous or monochromatic for calm, cohesive interfaces, with a single complementary accent reserved for the one thing you want clicked. Triadic and tetradic are vivid but hard to balance — they usually need one dominant hue and the others used sparingly.
Why does my triadic scheme look garish?
Because equal weighting fights for attention. The classic remedy is the 60-30-10 rule: 60% dominant colour, 30% secondary, 10% accent. Reducing the saturation of the two supporting hues also helps considerably.
Do harmonious colours guarantee accessible contrast?
No — harmony and contrast are unrelated. Two colours can sit in perfect triadic relation and still fail WCAG badly as text on background. Always verify the pairs you will actually use for text with a contrast checker.
