Can't Change Custom Color

No, UAC has no effect. Sorry, no more ideas... if that's your only problem, consider living with it, else start using a new user profile.

And maybe someone else can suggest sthg..
As I said you can try comparing differences between the working profile and yours, but you may end up wasting more time.

I understand i also would like to help you correct the issue instead of creating new user account but i'm out of ideas maybe other members can help you resolve the issue but i must say it does look like there is no solution to your problem.

Yeah, that may be right.
I have to try, or as Yoda would say... "do, or do not, there is no try."

This may be of help in place of that function:
Add Personalize (classic) context menu in Windows 10 Customization Tutorials

It should let you do more or less the same thing.

Did a "nuke-n-pave".
So whatever the issue was... it's behind me.
