Frequently Asked Questions

QWhat are color harmonies?

Color harmonies are mathematical relationships on the color wheel (such as opposites for Complementary, or 120-degree intervals for Triadic) that guarantee visually pleasing contrast and unity in design.

QCan I lock individual colors while randomizing others?

Yes! Click the lock icon on any swatch to keep that color fixed while generating new harmonies for the remaining slots.
