Color models

RGB model

A color model defined by three primaries; red, green, and blue. The RGB model is based on principles of trichromatic vision and additive color mixing.

Implementations & key differentiators

Display-P3 and sRGB have a different gamut. This results in more vibrant colors in Display-P3 compared to sRGB.

How it affects UI design

RGB color spaces are widely supported in most technologies, and are a safe approach to define colors for UI.

RGB color spaces are not perceptually uniform. Using these to mix tints, shades, or tones can be very difficult and yield unexpected results.

When trying to create perceptually uniform colors, use a color appearance model instead.
