As he puts it: “Our goal is to find a matrix M which will take a three-element vector representing an XYZ color and transform it to an equivalent RGB vector for some particular monitor.”

**The only information given to us will be the chromaticity coordinates x,y for each of the three phosphors, and for the white point.**
