I came across this link today that offers a ToolStripProfessionalRenderer implementation for the Office 2007 look-and-feel.
From what I can tell, it would be fairly straightforward (albeit tedious) to customize this to support various other themes, such as the silver and black themes of Office 2007.
More specifically, I'd like to find a color table that matches Visual Studio 2008. Does anyone know where I might find this?
