Do you also want to join the dark side? This is the theme I use.
Update: Download My customized Son of Obsidian Visual Studio color scheme for ReSharper
Download it from studiostyl.es/schemes/son-of-obsidian
Go to Tools > Options > Environment > Import and Export Settings
Check Use team settings file and click Browse…
Select the .vssettings file downloaded from above and click OK.

Done!
Note: When using the team settings file option the previous settings are preserved and can easily be restored by unchecking again.
