What is Harmony?
Harmony is a free color palette generator that instantly creates cohesive color schemes based on proven color theory principles. Whether you're a web designer, UI/UX professional, or branding expert, finding the right color combinations starts with one base color and a relationship on the wheel.
- Complementary colors: bold, contrasting pairs perfect for high-impact designs and call-to-action buttons.
- Triadic color schemes: three equally-spaced colors for vibrant, balanced designs.
- Tetradic colors: four-color palettes offering rich variety while maintaining visual harmony.
- Analogous colors: neighboring hues for cohesive, calming interfaces.
Every generated palette is copy-ready in HEX and hands off in one click: preview the full set on illustrations and layouts in Tones, verify text pairings against WCAG in CoCo, or compare against real-world systems in the Swatchy Brands Database. No signup required, and no limit on how many palettes you generate.
