Ribbon lines here:
ButtonShadow=0 0 0 ;explorer menu lines
The bad news is that the breadcrumbs navigation lines and the search bar are actually WindowText (the one you see mostly everywhere, in browsers, on desktop and when you type in notepads).
Making that one black and the theme is toasted: you cannot see a thing.
WindowText=224 224 224
;explorer breadcrumbs + search bar outline as well
So there is no solution in making that one black unless the backgrounds become white again but then we would be starting from the beginning again.
Anyway, I like how the ribbon group lines and inactive buttons are black now so that modified version is posted in zip.
