Frequently asked questions

Which harmony is safest for interfaces?
Analogous palettes are calm and easy to use; triadic adds contrast but needs careful role assignment for text and actions.
Are the generated colours accessible?
Harmony only describes hue relationships. Check text pairs with the contrast checker before shipping.
