Color spaces

CIELUV

A uniform color space created in 1976 by the International Commission on Illumination (CIE). CIELUV is an opponent color space.

CIELAB and CIELUV were both recommended as interim solutions for solving color difference specification of reflecting light.

Examples

HSLuv

HSLuv is a cylindrical transformation and adaptation of CIELUV created by Alexei Boronine.

How it affects UI design

Most uses of color in user interfaces are not affected by color appearance models. You do not need to rely on these color spaces to create aesthetically appealing and accessible colors.

Uniform color spaces are linear models of human vision. However, human perception is non-linear. Do not rely on these color spaces alone to create aesthetically balanced colors.

CIELUV and HSLuv are not supported by web browsers.

Color scales can be created by interpolation in various color spaces.

It is unclear why or when to use CIELUV over CIELAB, however it offers an alternative for color interpolation that may fit your needs.
