What harmony types are available?

Complementary, analogous, triadic, tetradic, split-complementary and monochromatic. Each rotates the base hue by set angles on the color wheel (monochromatic instead varies lightness).

How are the palettes calculated?

Hues are rotated in the OKLCH color space so the generated colors stay perceptually balanced rather than jumping in brightness. Colors that fall outside sRGB are clamped and marked.

Can I copy the colors?

Yes — click any swatch to copy its HEX value.

No. The palette is generated locally in your browser.

Harmony types

Complementary — the opposite hue.
Analogous — neighbors on the wheel.
Triadic / tetradic — evenly-spaced hues.
Split-complementary — the two hues beside the complement.
Monochromatic — one hue at several lightnesses.
