  4. Click any swatch to copy its hex to your clipboard.

What Is a Color Palette Generator?

Color theory groups harmonies by angular spacing on the HSL wheel as described by Itten's classic color system. Complementary pairs sit 180° apart for maximum contrast; analogous palettes stay within 60° of the seed for a unified mood; triadic places three hues 120° apart; tetradic uses four hues at 90°; monochromatic varies lightness on a single hue.

This generator is built for designers picking accessible brand systems, illustrators starting a new piece, and indie developers who need a credible palette without hiring out. Each output preserves the seed's lightness band so the result reads as a balanced set rather than five disconnected swatches.

The math runs in-browser, so seeds and outputs never leave your device — click Random for a cryptographically secure seed if you need fresh inspiration.

Frequently Asked Questions

Which palette types are generated?
Five harmonies based on the HSL color wheel: complementary (opposite), analogous (neighbours), triadic (120° apart), tetradic (90° apart) and monochromatic (same hue, different lightness).
How do I pick which harmony to use?
Analogous palettes feel calm and unified. Complementary palettes maximise contrast. Triadic and tetradic are vibrant. Monochromatic is the safest for UI.
Can I export the palette?
Each swatch has a copy button. Click to copy the hex code to your clipboard, then paste into Figma, CSS or your design tool.
