Make colors uniform across panels

I've searched yet was unable to find much in the way of the specific answer for which I'm looking. I think it's too vague of a question for the search function to properly narrow down the results.

Anyway, as the illustration shows I'd like to be able to have the same color on both 'panels'(?) in a lister.

Is this possible?

Turn off Preferences - Display - Fields: Current sort field.

Thanks!
