Strange colored previews that don’t match the exported photos in color managed programs are usually caused by a corrupted monitor profile. Lightroom uses the profile differently to other programs (perceptual rendering rather than relative colorimetric), so corruption in that part of the profile shows up in Lightroom even though it appears correct in other programs. It often happens with the manufacturer’s profiles that come with many monitors.
Check the Histogram on a grayscale photo. It should be neutral but corrupted profiles often create some weird color casts which also show on the Histogram.
Ideally you should recalibrate your monitor using a hardware calibration device. If you don’t have such a tool, put it on your shopping list, and in the meantime, remove the corrupted monitor profile to confirm that this is the problem.
Awesome! I installed a new graphics card last night and this morning noticed a yellow cast when viewing pics in Lrc Library AND Photoshop – but – they looked fine in Lrc Develop & Ps Camera Raw. I did a search and found this with your solution. Fixed <3
We’re delighted it helped you fix it!
Great. Changing the monitor profile following your recommendation did the trick. Thanks for helping. Strangely enough, the problem did not exist with the same old monitor profile in earlier Lightroom versions.
