Could the same be said about CIELAB? As far as I can tell, there are a good number of spaces that are superior in every way, explicitly designed for that very purpose?
Hi Jeff, as best I understand it, an important property of a chromaticity diagram space is that it be additive. i.e. that a blend between two primaries (or any other points in the space) lie on a straight line between those points. L*a*b* doesn't have that property, whereas Yxy and CIELUV do. You can certainly do projections of a gamut in L*a*b* space and they will be useful, but particularly in dealing with additive type devices like displays, it is a desirable property that you can reason simply about how primaries (or other points in the space) combine. Cheers, Graeme.
