Invisible Navigation Bar Buttons

CrDroid (and other ROMs as well) has an option to change navigation bar color according to the running app. With Aurora Store, it is set to white, however the buttons are also set to white, thereby rendering them invisible. With AuroraDroid, the navbar is set to gray.

I forget the app variable that the system reads to define what color should be used, so I'll check it. Once I post it, can you please change it to be the same as AuroraDroid, so as to allow the navigation buttons to be visible?
