Vic pointed me to a color scheme that you can just import into Visual Studio: http://www.winterdom.com/weblog/2007/10/13/RagnarokAVS2005ColorScheme.aspx
I really like it ... having a dark background with light text is a good color scheme if you tend to work in low light. I used to do it more often and it caused a lot less eye strain.
If you end up importing it, just make sure you bring the font-size a bit down, I don't know if the person who made that color scheme had a tiny monitor or what :-P
