I feel kind of stupid asking this, but what does this View option actually do? What gamut does it compare with. In LAB, for example, it shows things being OOG, but I'd be surprised if they were out of LAB's gamut.

Is it the default CMYK gamut? Is it settable?

This just has to be a FAQ.

gamut warning, that is said not to be very reliable, shows you the colors out of the gamut of the profile setted in the proof setup. for the reason you said you cannot set lab in the proof setup, it would never show any warning this way.

There actually are colors in the wider gamut RGB profiles that are outside of Photoshop's Lab -128 to 127 representation.

It's quite inaccurate (example: take an Adobe RGB file, convert it to LAB and ask it, without further changes, to show what colors are out of the Adobe RGB gamut--quite a lot, according to this option).

Even if it were perfect, however, I don't see any use for it--it would be reporting colors that are so mildly out of gamut as to create no problem, in the same manner as it reports grossly OOG ones that could wreck the conversion. Anybody who can't identify areas that are grossly OOG without the help of this tool is in big trouble IMHO.

It would be better if there were a control that allowed us to specify how *far* OOG the color would have to be before being displayed as such, but there isn't any formula at present that gives acceptable results--many darker colors that by current formulas are far OOG are not noticeable, but lighter ones whose numbers suggest they are closer might be quite objectionable.
