Random Colour Generator

Generate random colours as a free palette or a harmony built around a base colour.

A random colour generator produces colours either freely or within a scheme. Pastel, vivid and dark constrain saturation and lightness; analogous, complementary, triadic and monochrome build a harmony around a base colour by rotating its hue on the colour wheel.

Frequently asked questions

Why do purely random colours look bad together?

Because they have unrelated hue, saturation and lightness. Constraining any two of the three — the scheme options here — is what turns a random set into something that reads as a palette.
