Chromaticity (u, v)

u

0.160256

v

0.260114

(u, v) points describe chromaticity regardless of luminance, making them perfect for plotting lighting gamuts or locating correlated color temperature lines.

How to use the values

Plot chromaticity

Feed (u, v) into UCS diagrams to visualize gamut coverage, LED bins, or daylight loci.

Convert to temperature

Use the coordinates to approximate correlated color temperature (CCT) or Duv offsets in color research.

Chain conversions

XYZ values allow you to continue into LAB/OKLAB, compute Delta E, or match ICC profiles.
