Yeah, or around the axle might also have some tell tale red. RS did do some black ones for teams and bike co's though, albeit not that many, so it is possible that the black is original. Back in the day you were the cool of the cool if you had your lowers custom painted. These days it doesn't seem so common, sadly, as everyone wants factory orange or gold from Fox etc and would be too scared to lose street cred to change them!
