Random colour, three notations

Hex, RGB and HSL are three notations for the same colour. Hex is most compact; RGB is the underlying machine representation; HSL is the most intuitive for thinking about adjustments.

The generator uniformly samples the full RGB cube — every visible colour is equally likely. For brand-safe palettes, use the Color Palette Generator with a base hex you've picked.
