Is the colour palette generator really free?

Yes — completely. No sign-up, no email gate, no hidden Pro tier. The tool runs entirely in your browser, so there is nothing for us to charge for.

How does the AI build palettes?

Prompted palettes combine an LLM trained on colour theory with HSL-math smoothing, so the result is harmonious by construction. The non-AI fallback uses pure HSL relationships (complementary, analogous, triadic) — even when the AI is unavailable, the output is still musically correct.

Can I use these palettes commercially?

Yes. Hex codes are not copyrightable — colour values are free for any use, personal or commercial. Apply them to client work, brand systems, UI kits, packaging or print without attribution.

How many palettes can I generate?

Unlimited. Re-roll, refine or remix as many times as you like — no quotas, no rate limits and no API keys.

Are my prompts stored?

No. Inputs are processed in-browser and never sent to a server. Favourites save to your browser's localStorage so they survive a refresh, but they are not transmitted anywhere.

What format do I export in?

Hex codes by default, with one-click copy on every swatch. Each colour can also be inspected as RGB or HSL, and the full palette copies as a CSS variables block ready to paste into your stylesheet.

[ FAQ ]

Questions, answered.

+ Which harmony should I use?

Analogous for editorial calm. Complementary for sport, gaming, high-energy brands. Triadic for kids, food, lifestyle. Monochrome for luxury and minimalism. Split-comp for the colour-confidence of complementary without the visual fatigue.

+ Are these palettes accessible?

The harmony rules ensure good aesthetic balance, but not WCAG contrast guarantees. Always run any text-on-colour pairing through a contrast checker before shipping.

+ Can I export to Figma / Sketch?

Yes — copy the CSS block and import it via the Figma Variables panel, or use a tokens-to-Figma plugin like Tokens Studio.

+ Why HSL math instead of LCH?

HSL is supported everywhere with zero ramp-up. LCH produces more perceptually-uniform palettes and we may add it as a second mode in a future update.

+ Is the tool free?

Yes. No sign-up, no email gate, no Pro tier. Generate as many palettes as you need.

+ Will my colour leave my browser?

No. All palette math runs client-side. Your seed colour and the resulting palette never touch a server.
