Color Harmony Generator

Pick a base color and get matching harmonies from the color wheel: complementary, analogous, triadic, tetradic and split. Copy the hex codes you like.

A color harmony generator takes one base color and builds a matching set from the color wheel. Pick a base and choose complementary, analogous, triadic, tetradic, split or monochromatic, then copy the hex codes, so it works as a color wheel tool or a color scheme picker for a brand or a UI. The harmonies sit at fixed angles from your base, so the set stays balanced. It runs in your browser.

Frequently asked questions

What is a color harmony?
A harmony is a set of colors that sit at fixed angles on the color wheel relative to a base. Those relationships tend to look balanced together.
What is the difference between complementary and triadic?
Complementary uses the color directly opposite your base, 180° around the wheel, for high contrast. Triadic uses three colors evenly spaced 120° apart for a livelier, balanced set.
Which harmony should I use?
Analogous sets feel calm and cohesive, complementary sets feel bold, and triadic or tetradic sets give you more variety. Pick the mood you want, then tweak the base.
How do I keep the same brightness across the set?
The harmonies rotate hue while holding saturation and lightness steady, so the swatches share a consistent tone. Monochromatic instead varies lightness from one base hue.
