About this tool
Locking lets you iterate: keep what works, re-roll the rest.
Generated locally; nothing uploaded.
How it works
The generator builds palettes from color harmony rules on the HSV color wheel. Complementary palettes pair colors 180° apart for maximum contrast; analogous palettes take neighbors within 30–60° for calm, cohesive schemes; triadic palettes space three colors 120° apart for vibrant balance.
Values are emitted as HEX codes — the lingua franca of CSS, Figma, and every design tool. One click re-rolls the base hue for an entirely new color family.
Worked examples
Landing page: Generate a 5-color palette, then use the darkest for text and the brightest for your call-to-action button.
Brand refresh: Roll triadic palettes until one feels right, then lock the hue and fine-tune saturation by hand.
Quick reference

|---|---|---|

| Analogous | Neighbors within 30–60° | Calm, cohesive |
| Triadic | Three colors 120° apart | Vibrant, balanced |
| Split-complementary | Base + two neighbors of its complement | Strong but less tense |
| Monochromatic | One hue, varied lightness | Minimal, elegant |
