Go to Deviant Art, search for Concave in themes. (There is also a really cool icon pack for it that works on Macs and PCs.) I'd link you, but I'm at school and they block Deviant art here.. There are several styles, but I like dark the best. You wanted something white or black, and Dark is black. You'll have to patch your .dll, but thats pretty easy. Or use a styler installer, though most of those have trial periods. But if you put the theme on and your trial runs out, the theme is still there..
