Wrong color on display

Check if you have same issue while using safari or any other apps which you use most often.

Please mention the model/year of the Mac that you have the issue with.

Also check in safe mode if you have the same issue.

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.

What we did was basic troubleshooting. One more step is to check reinstalling macOS or update your macOS.

If the above step didn't help then please Contact Apple Support.
