How to use the harmony generator
- Pick a base color, or type its HEX value.
- Choose a harmony type — the color wheel shows how each generated color relates to your base.
- Adjust saturation, lightness, or (for analogous) the angle between hues.
- Check the live preview, then copy individual colors or export the whole palette.
What the output means
Each harmony type is a different rule for choosing related hues from the color wheel. Complementary pairs a color with its opposite for strong contrast. Analogous uses neighboring hues for a calm, cohesive feel. Triadic, tetradic, and square space hues evenly around the wheel for more variety. Split complementary softens a complementary pair. Monochromatic stays on a single hue and varies lightness instead.
Common use cases
Start a brand palette from one color, find an accent color that complements an existing design, or explore alternate color schemes for a UI mockup before committing to one.
Frequently asked questions
What is a color harmony?
A color harmony is a set of colors chosen using their relationship on the color wheel — such as opposite hues (complementary) or evenly spaced hues (triadic) — that tend to look pleasing together.
Which harmony type should I use?
Complementary and split-complementary work well for strong contrast and accents. Analogous and monochromatic tend to feel calmer and more cohesive. Triadic, tetradic, and square give more colors to work with when a design needs variety.
Are the suggested roles (primary, secondary, accent) required?
No — they're only suggestions to help you get started assigning colors to a design. Use whichever color for whichever purpose works best for your project.
Can I share a palette I've built?
Yes — your base color, harmony type, and adjustments are stored in the page URL, so copying the address bar link shares the exact palette.
