You can't see pinkies in your enemies team same way you see them in yours, and that is deliberate choice from devs, as that would make it hard to quickly get whether that pinkie you see right now is your pinkie, or is it your opponents one. However, starting recent major patch, you can see pink players in enemies team on loading screen before battle- point your coursor over name of an opponent, if that name is showed in pink- he's a pinkie
P.S. Point specifically on his name, not ship icon, and check color of pop-up text
