Why does the ‘Out of Gamut’ Warning appear only on RGB? My understanding was this was out of the gamut to what can be produced with ink or within CMYK anyway – So, for me, this has nothing to do with RGB so why does it appear here?
Your post makes no sense to me. Would you care to clarify it with details?
Sorry i was suppose to include images
here you can see RGB is giving me a out of gamut warning;
But CMYK isn't;
Gamut warnings apply ONLY when you work in RGB. They show you colours that can’t convert to identical CMYK. So you could never see a gamut warning if you’re already in CMYK. If converting to (or printing) CMYK definitely isn’t in your future the warnings can be ignored.
wow, this answer is very clarifying. Thanks!
It looks like you tried to post screen shots, but they didn't appear. You can drag screen shots into a reply or use this button:
Are you starting with HEX colors? If so, this article may be helpful.
I believe you can get a gamut warning in Photoshop IF you convert to CMYK in one profile but preview in another, wider-gamut CMYK profile (however slight the difference may be). For example, I converted an image using the default SWOP 2 profile and previewed the color with a FOGRA27 profile--lots of out-of-gamut areas. (I keep my images in RGB, so this isn't normally an issue for me.)
