Starting with Visual Studio 2010, it is now possible to change the color theme of the IDE. The color theme refers to the colors of the chrome or the skin or the various widgets of the IDE. The color theme does not refer to the text content inside the editor window, which are changed using styles.
The easiest way to play around with Visual Studio themes is to install the Visual Studio Color Theme Editor. After installation, open the Theme menu of the Toolbar for applying, importing or customizing themes. At the time of this writing the extension shipped with 8 themes.
Tried with: Visual Studio Color Theme Editor 1.3 and Visual Studio 2010
