PS Beta 27.8 — View/Proof Colors Not Acting As Expected

The View/Proof Set-up is allowing a profile to be selected (in this case Working CMYK) but the Proof Colors menu item doesn’t act globally and switches itself off between every image.

I’m not sure what Default profile it’s imposing but it’s very washed out and looks about 4 stops over-exposed. I must manually click the Proof Colors back on for every subsequent image. This certainly wasn’t the behavior in the previous version.

The correct answer was elsewhere in the forum. Turning off “Use Graphics Processor” in the Performance tab fixed it. BUT… it doesn’t matter because Adobe fixed it with this morning’s build of 27.8. (05/29/26)

I have the same issue and don’t understand the answer / fix. I am getting the washed out look too unless I use proofing colours - and yet when using the released version of PS no issues. Nor on Laptop when using previous beta version. I can't go Cmnd Y for every image - what did I miss please - I agree that something has changed. Tahoe 26.5, Mac mini, Eizo colour edge monitor. Beta 27.8

This worked for me:
View → Proof Setup
Set it to: Internet Standard RGB (sRGB)

d-fosse I very much appreciate you taking the time for a detailed response. I’m not a newbie at this. I’m actually old enough to have started PS on version 1.0 when it was bundled with BarneyScan. As great as ColorSync has been it’s not an exclusive path and as you pointed out it gets complicated quick. I use the Datacolor Spyder for a monitor calibration profile and that adds even more complexity.

Bottom line though is something changed in 27.8 that altered by working space. I guess I shouldn’t have assumed it was a bug.

Thanks again.

@media mogul11452452 if you feel it’s not working as expected, you should really report the issue on the Photoshop Beta forum

I thought “Ecosystem” included Beta and after looking around and not seeing it, I posed. I’ll move it. Thx.

Proof is a per-image and temporary/transient toggle switch. That’s how it has always worked, it has never been a global application setting.

As for the washed out appearance, what profile are you proofing to, specifically? It could also possibly be a defective monitor profile.

If it is a “per-image” switch then what profile is PS using when Proof Colors ISN’T selected? In Color Settings I use Adobe 1998 for RGB and have it set to “Convert to Working RGB,” All I know is everything was working just peachy before I updated the Beta to 27.8 and now unless I manually switch on Proof Colors for every single image, the image is washed out. Something changed.

What Photoshop uses is the profile embedded in the image. This profile, being embedded, travels with the file and is always used by any color managed application.

There should always, no exception, be a profile embedded in the image file, and it should be one of the standard color spaces: sRGB, Adobe RGB, ProPhoto RGB, or P3. These four should be correctly handled anywhere. Which one depends on the intended use for the file.

Your working space isn’t important! That’s just a default for new documents or missing profiles. The only important setting in Color Settings is Policies. I would strongly recommend “Preserve Embedded Profiles” - this is how color management is supposed to work. “Convert to Working” is risky because a profile conversion should always be initiated on a case-by-case basis. You always risk gamut clipping, and that should be a consideration before converting.

Then there is another link in this chain: your monitor profile. This is the second half of display color management, and it goes like this:

Document profile > (converted to) Monitor profile > Result sent to display.

The monitor profile describes the monitor’s native color space, just like, say, the Adobe RGB profile describes the Adobe RGB color space. It’s a straight-up profile conversion, executed by Photoshop on the fly, as you work. If the monitor profile is accurate, this ensures correct on-screen representation of the file.

Proof inserts the proof profile into this chain, so it goes like this:

Document profile > Proof profile > Monitor profile.

The purpose of this is to restrict the gamut to the proof profile’s gamut, so that you get a live preview on screen of any gamut clipping that you need to be aware of. This is not supposed to alter the general appearance, just show the clipping.
