I’m having the same problem, I installed a theme that I used with Firefox which makes most of the browser readable in light skin and black text, but the top bar (File, Edit, View, etc.) is unchanged, a very dark gray with black text, I have to be practically on top of it to read it in normal mode. It lightens up to light gray when I mouse over, but I’d rather it be light all the time. If someone knows a way to modify the color value of the background for that bar, I’d be most appreciative! I could make use of that bar for a weather app, but it’s not usable now because of the readability issue…a waste of perfectly good real estate IMHO.
