Random colour generator
Nearest named colour: olive
Calculated in your browser · nothing is uploaded
Generates random colours from your browser’s cryptographic source, held within a saturation and lightness band so they are usable rather than merely random.
How to use the random colour generator
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.
Questions
The draw is, but the range is constrained. Uniform random RGB produces mostly muddy greys, which is rarely what anyone wants.
Because saturation and lightness are held in a band. That is deliberate. It is what makes several random colours usable together.
Hex for anything going into a design tool, HSL when you want to adjust lightness by hand, and OKLCH when you need two colours to look equally light; it is the only one of the four where that number means what you expect.
Not necessarily. A palette generator arranges hues; it says nothing about contrast. Check any text-on-background pair against the contrast checker before shipping it.
The pastel, muted, neon, dark and light generators each constrain the bands differently.
