There was a simple solution in my case. The screen looked pink at certain times of day - hint, hint. Go to System Preferences > Display > Night Shift, and if it’s on, turn it off. I had turned it on with good intentions, but the color shift from sundown to sunrise seems far more drastic on a laptop screen than it does on an iPhone. I hope this solves your problem, too.
