I was bored one day an thought it would be cool to follow this tutorial to make my Finder windows look like Retro Mac OS Finder http://osxdaily.com/2012/03/20/simplify-os-x-finder-retro-mac-os-classic-style/.
I thought it would add to the effect if I made my Mac Grayscale by going into System Preferences > Accessibility > Display > Use Grayscale.
And then, as usual, I got annoyed by the theme and changed everything back.
Everything switched back nicely including grayscale. But then I noticed that on login, the color of files in Finder Windows and on the Desktop, when selected, was gray, the same color when in Grayscale. See pictures.
What it should be
What I've tried so far: - Restart
Disk Utility First Aid (Permission Errors in Plists)
Deleted Bunch of Plists in ~/Library/Preferences
I'm running macOS Sierra 10.12.6.
Also, when I change any of the following options it fixes the problem until next login:
Accessibility > Display > Use grayscale
Accessibility > Display > Increase contrast
Accessibility > Display > Invert Colors
General > Appearance
My Question: How do I completely stop grayscale so that it remains fixed even after a restart?
