Master Color Harmonies
Create balanced and visually appealing color schemes by applying proven color theory principles. Get complementary, triadic, analogous, or tetradic combinations in just a single click.
Find color harmonies for a hue
Enter a base color and instantly get its harmonies: complementary, triadic, tetradic, analogous, split-complementary. Each combination follows color-wheel rules for a balanced result.
Complementary, triadic, analogous harmonies
The tool mathematically computes each harmony from the original HSL hue. Visualize the derived colors and copy HEX, RGB or HSL codes in one click to use them in your mockups.
Build a consistent design system
Harmonies are the backbone of a controlled design system. Use complementary for CTAs, analogous for backgrounds and triadic for dynamic illustrations without visual disruption.
Interactive color-wheel preview
An interactive color wheel shows each harmony color's position. Change the base hue and watch the other colors evolve in real time: an excellent learning tool for color theory.
Free tool for designers and developers
Designers save time composing palettes, developers grab CSS-ready values directly.
