How To Use Color Harmony Generator

Choose a base color

Enter or pick the hex color you want to build a scheme around.

Generate the harmonies

The tool computes complementary, triadic, tetradic, analogous, and split-complementary variations.

Compare the schemes

Scroll through each harmony group to see how the base color relates to its counterparts.

Copy your favorites

Frequently Asked Questions

1. What color harmony types does this generate?

From a single base color, it generates complementary, triadic, tetradic, analogous, and split-complementary schemes — the core relationships from traditional color theory, all computed from hue rotation.

2. Which harmony type should I use for my design?

Complementary pairs create high contrast and work well for calls-to-action. Analogous schemes feel calm and cohesive, good for backgrounds. Triadic and tetradic schemes give more variety while staying balanced — useful for illustrations or data visualization.

3. Can I copy the generated colors directly?

Yes, click any swatch in any harmony group to copy its hex code to your clipboard.

4. Is this based on RGB or HSL color theory?

The harmonies are computed in HSL space by rotating the hue value while holding saturation and lightness constant, which matches how traditional color-wheel relationships are typically defined.
