Has anyone had any success with ColorSync's gamut checking functions?
ColorSync seems to have a very small tolerence. Photoshop's gamut check
feature shows many more colors are in gamut than what ColorSync does. Is
there a better way to check if a color is in gamut than by using
CWCheckBitmap or CWCheckColors, or has Adobe got it wrong?

For what it's worth, I've seen this as well: lots of colors out of gamut.
Very light colors in particular seemed to be placed out of gamut, which
didn't make sense to me. We decided not to pursue the feature that needed
this, so I haven't investigated further.

I'm starting to think the same thing. Even in PhotoShop, I'm not sure what
user's are meant to do to put their images back into gamut without
converting to a profile. I'll send this to the ColorSync User's list to see
what they think.

Does anyone find gamut checking a useful feature?
