Photographs contain colors with RGB numbers like 212,116,84; vector colors
defined numerically by illustration and layout programs tend to have numbers
like 255, 0, 255. Photos seldom stretch the gamut limits and illustrations
generally do. Thus my reference to "photo" and "vector" colors. Two profiles
with very different looking gamut outlines may print a controlled gamut photo
very similarly, but might print a spectral gradiant of maximized color
numbers very differently; especially if one of them was built using a scanner
based profiling package.
Ah, yes
The gamut boundary is a strange place to be when rendering color.
Unpredictable yet often used for profile evaluation so can be
misleading..
