Change background color for notification entries?

Samsung Galaxy 5 (aka 550, Europa, Corby), Samsung's Froyo version (so, Touchwiz. Launcher is ADW Launcher (non-EX). My notifications (the things in the list when you pull down the notification bar, if that's the proper terminology I have no idea) are all black on dark gray, and I'd like to change it. I don't know if it's even possible w/o hackery. Phone is rooted, upgrade to CM7 or higher is "planned" (for some time now :D). So, if it's possible to make the notifications more readable there, that would be a solution. The only readable notification is black on white (or blue on white, not sure), and it's from TaskXP. So the colors seem not to be hardcoded. And as always, a RTFM is welcome. When it includes pointers to *where* in the FM the info is.
