sRGB IEC61966-2.1 Color Profile and Photoshop 24 25.2.0

I just did a clean install on a new Mac Mini, so Photoshop's just been loaded.

For years, as I recall, the sRGB variant in the "recommended" folder installed by Adobe has been called "sRGB IEC61966-2.1" - now in my "recommended:" folder there's just one sRGB and that's: "sRGB Color Space Profile.icm"

Anyone else seeing this?

We've been telling users to be careful to use "sRGB IEC61966-2.1" but now it seems Adobe may not be installing it.

Correct answer NB, colourmanagement

@c.pfaffenbichler interesting that you spotted that and - how strange, the Mac finder doesn’t agree with the Colorsync Utility on the 'external' name

- when I open it in the Colorsync Utility it reads like this (as did yours)

something wrong at Apple!

In the arguably more sophisticated Colorthink Pro 4 beta I see this

(which reports the external (finder) name correctly 😞

same in Colorthink Pro 3, reports the external (finder) name correctly

@D Fosse you're right about mismatching of the internal and external names, but as @c.pfaffenbichler discovered the Apple Colorsync Utility fails to reveal the mismatch - actually showing the external name incorrectly!

The working space in Photoshop is irrelevant. It's just a default for missing profiles. It will open into Photoshop in the color space specified in Lightroom Preferences > External Editing. The two do not need to match.

In any case, this is almost certainly not a problem with the document profile - it's much more likely a problem with the monitor profile. Check that the correct monitor profile is loaded into the operating system. PS and Lr use the monitor profile they get from the operating system at startup.

Also check that the profile made by the BenQ software is matrix-based, not LUT (table) based. MacOS doesn't work well with matrix profiles. In the same way, set it to the v2 specification, not v4.

If you show screenshots it would help narrow it down.

Has there been any development on this?

I'm running LR and PS on an M1 studio with Benq monitor calibrated using xrite I1 and the BenqPaletteMaster.

Opening the same file in LR DEV mode into PS with working space in Prophoto, the images appears different.

both apps in respective windows on the same single screen.

Adobe is telling me that SRG IEC61966.2.1 needs to be in the profile folder but the folder is only showing "sRGB Color Space Profile.icm"

Adobe claims this srgb profile is responsible for the two apps showing the same iamge dfifferently even though I'm working in Prophoto with a calibrated display profile.

@Matthew36770370py29 My original post was about Adobe having seemed to rename the sRGB profile, Photoshop installs the current Adobe version of sRGB to the 'recommended' subfolder

That should be here on your mac:

So, Photoshop now apparently installs "sRGB Color Space Profile.icm" (that’s the finder file-name - confusingly the profile has an "internal" name of 'sRGB IEC61966-2.1' (see above on internal and external names) you should see the "internal name" in applications, including Photoshop - I see it in Photoshop 25.

Colorthink Pro software shows this on naming of that profile:

In any case - @D Fosse is right, this should not affect you at all - the default working space in your Photoshop color settings is only a default for documents (images) which are opened with no profile embedded (i.e. untagged) or for new documents created in Photoshop.

It does not affect the display of an open document (image) which has an embedded colour space, you mentioned Prophoto, I presume that’s embedded in your image file .

The BenQ pallet master software has caused issues for a lot of users, since that what you are using it could be at the root if this

Please also be sure on profile type - as @D Fosse wrote " check that the profile made by the BenQ software is matrix-based, not LUT (table) based. MacOS doesn't work well with matrix profiles. In the same way, set it to the v2 specification, not v4."

I hope this helps

That profile seems to have the other name anyway.

This is probably just the "internal" and "external" profile name, which has confused people always.
