Using an existing Sublime 2 color scheme, is there a way to tweak the background color selectively for eg. .js files only? Many thanks!
You have to modify your .tmTheme
color scheme plist
. You can find it with menu Preferences/Browse Packages...
, Color Scheme - Default
directory.
You should add something like this:
<dict>
<key>scope</key>
<string>source.js</string>
<key>settings</key>
<dict>
<key>background</key>
<string>#000000</string>
</dict>
</dict>
as a child of the settings array (of course you have to change #000000 with your color code).
