Color Models

Color Space

A specific mathematical model that defines a range of representable colors using a coordinate system.

A color space maps abstract color values to concrete, reproducible colors. It includes a color model (like RGB or Lab), a set of primary colors or reference points, and a transfer function (gamma). Common color spaces include sRGB, Adobe RGB, Display P3, CIELAB, and OKLCH. Different color spaces exist because different media and use cases have different requirements. sRGB prioritizes consistency across consumer devices, while CIELAB prioritizes perceptual uniformity. Choosing the right color space for a workflow is fundamental to accurate color reproduction.
