Recently I started moving projects to Visual Studio 2010, but I found it hard getting used to its new color scheme, especially because I keep using 2008 daily. To me, compared to the 2008 IDE, the whole thing is just depressing with all the dark colors, just like the Expression Blend lights out theme. It might be an acquired taste like beer, but I can't stand that either. :) Fortunately there is an extension in which you can change the IDE color theme or create your own, so I got to it and modified the Windows Aero theme to look more like the 2008 IDE. I think it's close enough, the file tabs couldn't be matched due to a different tab rendering method it uses, but I'm satisfied with the result.
To use this theme, you have to install the Visual Studio Color Theme Editor extension and import the unzipped vs2008.vstheme file with it.
