That may well be the theory...but, in practice, it's not the case. See some of the earlier examples I posted -- for example, the one where R=G=B=1 got mapped to cyan. I'll bet you a cup of coffee or other suitable beverage that adding a D50 patch to the .ti3 that produced that profile would fix the problem entirely. Cheers, b&
