Your Colorful Visual Studio 2012 with the Color Theme Editor (VS2010 colors, too)
The stock Visual Studio 2012 gray color scheme is growing on me. Sue me. When you're writing code you usually focus on the code so I'm more concerned with the colors of the code than the chrome.

Have fun! Go get Matthew Johnson's Visual Studio 2012 Color Theme Editor now.
UPDATE: I personally would not go this far, but you can also patch the icons if you feel strongly about it. http://vsip.codeplex.com
