Generate harmonious color schemes from color wheel theory: complementary, analogous, triadic, split-complementary, tetradic, etc., for quick, cohesive UI or brand palettes.
This tool builds a set of harmonious colors from a base color and shows their relationship on the wheel plus HEX/RGB values for use in design or code.
Enter or pick a base color (HEX, RGB, etc.); the tool computes harmonious colors on the wheel. Adjust hue, saturation, and lightness to tune the overall feel.
Select a scheme: complementary (opposite), analogous (adjacent), triadic (120° apart), split-complementary, tetradic, etc. Each type produces a fixed number of hues with a clear relationship; swatches and wheel are shown.
View the palette and HEX/RGB values; copy a single color or the full set into design tools or CSS variables. Some tools export JSON or a CSS variable list.
Complementary colors sit opposite on the wheel (e.g. red vs. cyan), high contrast; analogous are next to each other (e.g. red and orange), more unified. Choose by brand or UI style.
Yes. The tool usually fixes hue relationships; you can adjust lightness and saturation after copying, or use in-tool sliders if available before export.
Good as a starting point; for UI you still need to consider contrast, accessibility, and roles (primary, accent, background). Refine or add shades from the harmony set as needed.
