Raptor 7s tongue discoloration

Anyone here ever have a problem with this? A pair of Raptor 7s I received had some weird discoloration on the tongue. Normally, its supposed to be black and different shades of grey/silver but mine look more brown than black and not silver at all. If it means anything, the part of the tongue that is under the flap is the right color, just the exposed part isn't.

Was just wondering if this kind of tongue discoloration is common on the 7s or if the pair I have is fake.. (which I don't think so but could be a possibility).

Will post a pic soon
