How can I change the font and color settings for js files in Visual Studio 2010?

VS2012 - Javascript Display Items:

Identifier = "All JS Identifiers"

Keyword = "All JS Keywords, i.e.: var, if, else, this"

String = "all string items"

Comment = "all comments in JS"

Open the IDE options dialog: Tools | Options | Environment | Fonts and Colors

In the Display Items list, look for items that start with "Script"
