About this tool
What it generates
The tool produces random colors across the full hue, saturation, and lightness space, showing each as a swatch with copyable HEX, RGB, and HSL values. Generate one at a time or in batches — every result is a color your habits would never have chosen.
When to reach for it
Break palette ruts by sampling colors outside your defaults, generate distinguishable test colors for UI development, assign random-but-copyable colors to categories or tags, or seed a brainstorm before curating down. Randomness is a research tool, not a final answer.
From random to on-brand
Generate broadly, then normalize: run promising picks through the color converter to set your system's saturation and lightness, keeping only the random hue. Need two randoms that work together? Blend your favorites to check their midpoint before committing.
Frequently asked questions
Are generated colors repeated?
The space is enormous — over 16 million colors — so repeats are effectively impossible in a session. Treat every generation as unique.
Can I generate colors matching my design system's saturation?
Not directly — the tool randomizes the full space. Generate hue candidates, then set saturation and lightness per pick with the converter.
Is there a limit on how many I can generate?
No — generate freely. Everything runs in your browser, and there is nothing to count.
