How does color mixing work?

Color mixing combines two or more colors into a single blended result. The method of blending significantly affects the output. RGB mixing (the default for screens) averages red, green, and blue channel values directly. Perceptual color spaces like LAB and LCH model colors closer to how the human eye perceives them, producing more natural-looking midpoints — especially when mixing saturated or strongly contrasting colors.

LAB (CIELAB) separates lightness from color information using three axes: L (lightness), a (green–red), and b (blue–yellow). LCH is a polar form of LAB that represents chroma (saturation) and hue angle, making hue interpolation smoother for vivid colors.

Tool description

This tool blends two or more colors together using weighted mixing in your choice of color space: RGB, LAB, or LCH. Assign a percentage weight to each color to control its contribution to the result, then see the mixed output as a swatch with hex, RGB, HSL, and other color values.

Features

  • Mix any number of colors with individual percentage weights
  • Three mixing modes — RGB, LAB, and LCH — for different blending characteristics
  • Output displayed as a color swatch with multiple format readouts
