Wrong color displayed

[brucekorb]

The thumbnail in the upper left has the correct color. LR-Classic is in develop mode. In fullscreen mode, the colors are also correct. I exported a JPEG, also with correct colors. It's just the develop module.  The 600Mb TIFF file is too big for here, so I'll leave it on Google Drive for a few days. Let me know when you've downloaded it so I can remove it. Thanks.

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. 

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If thi deosn't help try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this also doesn't help, plaes cherck your monitor profile.

This is a one-off problem. I've never seen it with any other image. A am assuming that Adobe would like to fix the problem. For me, I don't care unless it crops up with other photos. I've exported the JPEG to the person I needed to. get it to. (Some yokel doesn't believe there's enough space to install an 8X8 box on my garage wall.)

The colors are identical in my LR 12.4, PS 24.6.0, and the Preview app on Mac OS 13.4 / Apple M2 Max (see screenshot below).

As described by Axel above, the two most common causes for blatant color mismatch between Develop and Library and other apps are a buggy graphics driver and a defective or incompatible display profile.

As recommended by Axel Matt above, quickly test for problems with the display profile by temporarily assigning the sRGB profile to your display. The link Axel provided has way-out-of-date instructions for Mac (Lightroom Queen is fixing it soon). See here for almost-up-to-date instructions for Mac OS 13:

You can partially test for a buggy graphics driver by setting Preferences > Performance > Use Graphics Processor to Off.  The Radeon Pro 580 is 6 years old, and AMD may not be prioritizing bug fixes for it.

Thank you. Whatever is going on, the develop module must be presenting different data to the graphics driver from the other methods (Photoshop, LR full screen, Apple's Photo, or anything else for that matter). That seems pretty curious to me -- why would the develop module be doing that? SO, ok, if I bump into this again, I'll turn off the graphics processor to see if that fixes it and, if it works, do that when necessary. I don't have plans to spend several thousand dollars to replace my fairly recent iMac because of this. It nevertheless seems peculiar to me that the develop module develops different data to describe the same image to the graphics driver. But thank you for the info.

P.S. Since uploading the TIFF, I merged the two layers in Photoshop and turned off the visibility of the original layers. The result was unchanged: blue became red fringed with blue.

[johnrellis]

Develop and Library have two completely different code paths for displaying images.   Library displays previews saved in JPEG format in the preview cache and is optimized for speed, while Develop shows the image generated in real time from all the current develop settings. They also use different color spaces.

"The 600Mb TIFF file is too big for here"

Why can't you resave it as jpeg at a smaller size? The wonky colours will be the same.

If you read the complaint, you'll notice that there is no problem with thumb nails, full screen *or* JPEG exports. The _only_ way to demonstrate it was with a screen capture.
