Complementary Color Calculator
Find the complementary (opposite) color on the color wheel for any hex color.
How to use this tool
- Enter a hex color.
- The tool inverts each RGB channel (255 − channel) to find the complement.
- Use complementary colors for high-contrast designs or call-to-action buttons.
The complementary color sits directly opposite your color on the color wheel. It creates maximum contrast and vibrant, high-energy combinations.
Frequently asked questions
- How is the complementary color calculated?
- By subtracting each RGB channel from 255. This rotates the hue by 180° on the color wheel.
- Are complementary colors the same in all color models?
- In RGB, the complement is the bitwise inverse. In RYB (traditional art), complementary pairs differ slightly (e.g., orange complements blue-violet).
