Random colour generator

Generates random colours from your browser’s cryptographic source, held within a saturation and lightness band so they are usable rather than merely random.

Truly uniform random RGB is almost never what people want: it produces a lot of muddy near-greys, because most of the RGB cube is unsaturated, and it wanders in lightness so the results cannot sit together. Constraining saturation and lightness fixes both. If you genuinely need uniform random RGB — for testing, or to demonstrate the point — that is a different requirement, and worth knowing this tool is not doing it.
