Hmm, I've been using a value of x:0.345653 y:0.358596 when generating my profiles rather than the CIE D50 values of x:0.345703 y:0.358539 -- I'll fix that now. I assumed 5003K was exactly equal to D50. > you get is so low that can be ignored. For D65, I use the CCT > black-body radiator formula on 6504K as described by CIE. Really, > should be around 6503.6K Do either of you know where the CIE refers to D65? I see an example as "WhitePoint [0.9505 1 1.0890]" in the EPS example, but nothing approaching a standard. Also, do you have exact xy coordinates for either 6504K or 6503.6K handy? I've been using cmsWhitePointFromTemp (&w, 6504) but I'm wondering if that's accurate enough.
