Is not a gamut a limit? Restricting gamut to certain coordinte systems doesn’t
make it any less a limit. Restricting ‘gamut’ to a jargon definition doesn’t
erradicate ‘gamut’ as an applicable term for describing color bounds or
capabilities.
Gamut is a broader term than it has been reduced to by some in this thread.
Sorry if this doesn’t fit the model for some color scientists but that’s the
way it goes. If a group wants to own language then they’re bound to run into
ignorant people like me. It’s the price you pay for ownership.
