Definition

The coordinates of the CIE 1960 UCS diagram are calculated from the 1931 CIE XYZ tristimulus value or from the xy chromaticity coordinates thus:
$$ \begin{array}{l}u=4X/\left(X+15Y+3Z\right)=4x/\left(-2x+12y+3\right),\\ {}v=6Y/\left(X+15Y+3Z\right)=6y/\left(-2x+12y+3\right).\end{array} $$
