Common LAB colors for quick conversion

Input

Enter CIELAB values to convert to CIE XYZ color space.

Lightness (L*)

a* (Green–Red)

Green (-128)Red (+127)

b* (Blue–Yellow)

Blue (-128)Yellow (+127)

How it works: Converts CIELAB to CIE XYZ using the inverse LAB transformation. LAB's perceptual uniformity makes it useful for comparing color differences and performing color corrections.

What is LAB to XYZ Converter?

The LAB to XYZ Converter transforms CIELAB (L*a*b*) color values to CIE XYZ using the standard conversion formulas and D65 reference white point. CIE XYZ is an intermediate color space used in conversions between LAB and RGB. The tool accepts L*, a*, b* inputs and produces X, Y, Z values. All processing happens in the browser.

How does LAB to XYZ Converter work?

This tool implements the LAB-to-XYZ conversion formulas: it computes the f-inverse functions from L*, a*, b* using the D65 reference white (X=0.95047, Y=1.0, Z=1.08883), then recovers X, Y, Z through the piecewise function.

Pro Tips

1
L* is lightness (0-100). a* is the green-red axis. b* is the blue-yellow axis.
2
The D65 white point is the standard for sRGB and most modern color work.
3
XYZ values are typically in the range 0-1 for normalized data.
4
Combine with an XYZ to RGB converter for a full LAB to RGB pipeline.
