Random HEX color generator
Generate one accent or a small random palette, lock the keepers, and copy HEX, RGB, or HSL. Useful when you want a starting color before you refine it in the picker or check contrast.
Frequently asked questions
- How random are these colors?
- Each channel is chosen with crypto.getRandomValues() when the browser provides it, otherwise Math.random(). Batches retry briefly to avoid duplicate HEX values.
- What does lock do?
- A locked swatch is kept when you generate again. Unlocked swatches are replaced. The large preview always shows the first color in the batch.
- Is there a seeded mode?
- The public UI uses live randomness. Seeded helpers exist in the color library for tests so fixtures stay stable.
- Where is history stored?
- HEX history is stored in localStorage on this device. Clear history removes it. Values are not uploaded.
- Can I export a random palette?
- Yes. Copy the HEX list or download CSS variables and JSON.
