<As you know, these three Gamut Mapping choices only apply to Perceptual.>
<Do you mean to say that, as long as one uses Relative or Absolute
Colorimetric, or Saturation intents, and not Perceptual, the choice of Gamut
Mapping method is irrelevant, and has no effect on the results?>
I can verify that the Colorful and Chroma-plus gamut mapping choice in
Profile Maker 5.0.2 appear to be identical using rel col. The Classic mapping using
rel col is indeed different, however. Viewing a Granger rainbow with all three
mapping options, the Classic option doesn’t appear to have the “hole”
in the blues that the other two exhibit, but suffers from pretty strong blue desaturation
overall instead.
