Interactive Color Wheel - Complementary & Analogous Color Schemes
This color wheel online tool reveals complementary, analogous, and triadic matches from any base color. It is the fastest way to build harmony without guesswork.
Pick a base, inspect the relationships, and export the palette to your design system or UI kit.
What is the color wheel?
The color wheel maps hues in a circular model so you can see relationships between colors. It is the foundation of harmony rules used in branding and UI design.
By moving around the wheel you can create calm, energetic, or high-contrast palettes based on the spacing between hues.
Complementary colors
Complementary colors sit opposite each other on the wheel. They create strong contrast and are ideal for calls to action or attention-grabbing elements.
Use complementary pairs sparingly so the palette stays balanced rather than overwhelming.
Analogous and triadic schemes
Analogous palettes use neighboring hues for smooth transitions, while triadic palettes balance three evenly spaced colors for lively, controlled energy.
Using harmony in branding
Harmony reduces visual tension and makes a palette feel intentional. Start with one base color, derive harmony matches, then test contrast for accessibility.
From wheel to UI system
Assign each harmony color a role: primary, secondary, and accent. Then lock in contrast pairs so UI components remain legible across themes.
