A friend sent me a link to Tomas Restrepo's collection of VS Color Schemes today.  I think it's a fantastic idea.  I like to use a dark background, but there sure a lot of settings that need to be changed in order for it to be usable.  Especially if you use C++/C#/XML and XAML, which all have their own colors that need to be set...

I'll definitely be giving some a try when I get back in the office on Wednesday.  So far I think Ragnarok Blue looks like it'll be my favorite.
