Palettes that actually go together

Each color is computed with HSL math from a seed hue, analogous, complementary, triadic, monochromatic and shade modes follow real color-theory relationships, while Auto mixes them up for happy accidents. Lock the swatches you want to keep and reroll the rest, fine-tune any color with the picker, then grab hex, RGB, CSS variables, a PNG strip or a shareable link. It all runs on your device and your last palette is remembered automatically.
