What is a complementary color?

A complementary color is a color that sits directly opposite another color on the color wheel. When placed next to each other, complementary colors create maximum contrast and visual impact. This concept is fundamental in color theory and is widely used in art, design, and photography to create balanced, eye-catching compositions.

Color Theory Details

Complementary Colors (180° on the color wheel):

  • Create maximum contrast when placed together
  • Balance warm and cool tones
  • Make each other appear more vibrant

Spread Angle Settings:

  • Small angles (1-15°): Generate subtle color variations, perfect for monochromatic-style palettes with slight hue shifts
  • Medium angles (15-30°): Create noticeable but harmonious color differences, ideal for balanced designs
  • Large angles (30-60°): Produce bold color contrasts while maintaining the complementary relationship

The tool generates colors centered around the complementary position (180° from your input), distributing them evenly based on your chosen spread angle.
