Ben, btw, do you really have a scenario where you know the reflectance spectra of a set of patches, and also know the XYZ colors emit these patches when illuminated by an unknown light source, but where you do not know the light source spectrum?

The assumptions should be likely though, for the given scenario, in order that the found solution is likely the correct solution, or close to the correct solution. Regards, Gerhard
