How to change background color for selected folder/file in Outliner and Binder?

I had to changed to a different computer and lost my previously saved themes and layouts. Now I’m trying to recreate it, but can’t seem to find the option to change the change background color for selected folder/file in Outliner and Binder. I looked in the options/appearance/colors for binder and outliner, but they didn’t have the option I’m looking for.

It’s in the menu
View
Use Label Color in
Binder F5
Show as Background Color in Binder

Sorry I missed the reply. I’m asking about when the file is actually selected/highlighted. It’s a blue color by default, but there doesn’t seem to be a way to change that highlighting color when a file is selected in the outliner and binder.
