I believe that NSColorPanel dispatches the -changeColor: action method using -[NSApplication sendAction:to:from:]. Therefore, you should be able to use a custom application object (subclass of NSApplication) with an override of that method which short-circuits for that selector (perhaps only under certain circumstances).
