About Palette Generator

The Palette Generator builds a coordinated palette from a base colour and a harmony rule, copying any swatch’s HEX on click. It is for designers assembling a colour scheme that works together.

Harmonious palettes follow colour-theory relationships that are tedious to calculate. Generating them locally from a rule produces a coordinated set instantly.
