So I painted my white trim red to match the walls but I am not sure I like it. Should I go back white? Or maybe black? Please help
my room has the same colors - i would go black base boards - on the red walls it is an accent color and on the screen wall it blends in and is not a visual distraction.
+1 for black.
Then get some black outlet / keystone plates to replace those white ones on the screen wall, too.
Black for the win
Black, the red is drawing your eye away from the screen and competing for attention. It should just blend into the screen wall.
Black, unless for some reason you want to draw the eye there ;-)
