There is a custom syntax color theme maker for Visual Studio here: http://studiostyl.es/schemes/create http://studiostyl.es/schemes/create.

However, that page is not very good for creating dark-background themes. It’s missing a bunch of styles that I saw fairly often in C# code, and their default light colors look awful on a dark background.
