Palette Generator

Color

Generate harmonious color palettes

Starting from one base color, this generates a harmonious palette using standard color-wheel schemes (complementary, analogous, triadic, monochromatic) by rotating or adjusting hue and lightness around that base, useful for a UI theme or brand color scheme. You can lock a color you like partway through and regenerate the rest around it, which is a faster way to refine a palette than starting over from scratch each time, and export lands as HEX values ready to paste into a CSS variables file or design tool. It's focused purely on color harmony, not accessibility. It doesn't check contrast ratios between the colors it produces, so any text/background pairing pulled from a generated palette should still get run through a dedicated contrast checker before shipping. Generation runs entirely client-side.

Frequently asked questions

What color harmony rules does it use?
Standard color theory schemes are supported — complementary, analogous, triadic, and monochromatic — each generated by rotating or adjusting hue/lightness around your base color on the color wheel.
Can I lock specific colors while regenerating the rest?
Yes, locking a color keeps it fixed while the rest of the palette regenerates around it, useful for refining a palette without losing a color you already like.
Does it check for accessible contrast between palette colors?
No, this tool focuses on color harmony, not contrast ratios — use a dedicated contrast checker to verify any two colors meet WCAG AA/AAA requirements before using them for text and background pairs.
Is my palette data sent anywhere?
No, palette generation happens entirely in your browser.
