Sublime 2 -changing background color based on file type?

Question

Using an existing Sublime 2 color scheme, is there a way to tweak the background color selectively for eg. .js files only? Many thanks!

Answer 1

I was actually trying to change the background color for text files and was wondering how Riccardo figured out how to use source.js as the value for the scope.

You need to locate the .tmLanguage file of the file type you are trying to change, which is "Plain text.tmLanguage" for text files. Then look for the scopeName key and use the value for that. This is from my "Plain text.tmLanguage" file:

scopeName
text.plain

So, for example, to change the foreground color for text files to lime:

        scope
        text.plain
        settings
        
            foreground
            #00FF00
