True, but they need to know that what they want is equivalent to using sRGB. They want a "don't bother me with any of this" setting because they really don't know or don't want to know any of it. > But if there really is a defensible use case, here are two concrete > suggestions: > > 1.

That's exactly what is confusing to them :) "What is sRGB again?" > Here is why I'm making these two suggestions: > > GIMP menu items and help hover tips shouldn't misinform GIMP users, > but > instead should tell GIMP users the truth and also help to educate > them. I agree, and propose to have tooltips that disabling is the same as using the built-in sRGB profiles. > In an ICC profile color-managed editing application, pixels are > literally meaningless without knowing which ICC profile should be > used > to give the channel values meaning.

But it does, it really does in the code. no profile == sRGB. > The global switch in "Preferences/Color Management" to set the Image > display mode to "No color management" actually does disable color > management.

That switch is *only* for display color management, If you disable it, things are still properly converted if you copy pixels between images. > Unchecking the pre-checked box in the "Images/Color Management" menu > that says "Enable Color Management" sounds like it should do the > exact > same thing as going into Preferences and setting the Image display > mode > to "No color management".

I just reorganized the prefs page and it should now be clearer that it is meant for display settings only. > The truthful and less confusing verbiage for this prechecked > "Images/Color Management/Enable Color Management" option would be > "Images/Color Management/Assume this image is an sRGB image". We can have a tooltip saying so, but using that suggested wording defeats the "don't bother me, I don't want to understand it" purpose of the setting. > Also, the position of the new option gives it "mouse scrolling" and > "visual" importance.

So the new option is at the right place. Sorry, but I'm 100% convinced that the vast majority of users has no clue whatsoever about color management. Heck they can't even distinguish pixels from DPI. A simple was to turn it off is IMO exectly what's needed. > This prominent placement of the new option in the "Image/Color > Management" menu makes it seem like a normal thing to do while > editing > an image is to disable Color Management, which of course isn't at > all > what this option really does. It switches to default things and that's all it can do, there are no pixels without meaning ever since we made color management omnipresent in GIMP. > So again, if this new option really does have some utility (and again > I > can't see that it does), then it would be better to do the following: > > 1.

Relabel the option as "Assume this image is an sRGB image". That definitely not, but I will immediately add tooltips saying that it is the same as choosing sRGB.
