Color Harmony Generator
Generate complementary, analogous, triadic and other harmonies from a base color.
Color harmonies are the color wheel's proven recipes for combinations that look intentional rather than accidental. Rotate the hue by fixed angles — 180° for complementary, 120° for triadic, 30° for analogous — and you get palettes that designers have relied on for centuries.
Enter any base color and this tool generates six classic harmonies at once: complementary, analogous, triadic, tetradic, split-complementary and monochromatic. Each swatch shows its hex code for copying straight into your design tool or stylesheet.

Frequently asked questions
Common mistakes to avoid
- Using every color in a harmony at equal strength — pick one dominant, one secondary, and use the rest as accents.
- Ignoring contrast: a harmonious pair can still fail text-legibility checks. Verify with the Contrast Checker.
