Pick one base color and it automatically calculates complementary, analogous, triadic, and tetradic color schemes based on color wheel theory. It shows each scheme's HEX code so you can easily find harmonious color combinations.
How to use
- Set your base color with the color picker or the HEX input.
- Complementary, analogous, triadic, and tetradic schemes each appear automatically.
- Copy a single color or an entire scheme's HEX to use.
FAQ
- How do the schemes differ?
- Complementary is the exact opposite (180°), analogous is nearby (±30°), triadic is 120°, and tetradic is 90° apart—each suited to emphasis, a calm feel, or a varied composition.
- Are the base color's brightness and saturation kept?
- Yes. It rotates only the hue and keeps the saturation and lightness identical to the base color for a unified scheme.
- Is the color I enter sent to a server?
- No. All scheme calculations happen inside your browser, and no information is ever transmitted or stored on a server.
