HEX to LAB Converter

How HEX to LAB conversion works

CIE L*a*b* (often written LAB) is a color space designed to be perceptually uniform — equal numeric distances between two LAB colors correspond much more closely to equal perceived differences than RGB or HEX do. That makes it the standard choice for color-difference calculations (Delta E), print/design color matching, and image-processing pipelines.

This tool converts your HEX color to sRGB, removes the sRGB gamma curve to get linear RGB, transforms it to CIE XYZ using the D65 standard illuminant, and finally derives L* (lightness), a* (green–red axis) and b* (blue–yellow axis) using the standard CIE 15:2004 formulas — entirely in your browser.
