# 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.

## FAQ

### 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.
