My current .emacs includes this:
(custom-set-faces
...
'(scroll-bar ((t (:foreground "yellow" :background "black"))))
...)
Via the customize-faces command, I could only figure out how to check and uncheck the foreground and background colors (so I guess I don't know what I am doing with that). It had the background already in there, so I hand-edited .emacs to add the foreground and make that contrasting, as I am used to hand-editing my .emacs. Anyway, all of this came to no avail.
Is there somebody out there in net land that can help me with this?
