They do have bloodshot eyes, and their ethnecity seems to be very dark. They could have originally been caucasian and have their skin darkened from the radiation or it could just be that they all have different skin colours.

Also, their masks are made from bone. When they looked at the bones earlier the skull was deformed. These were most likely Grounder skulls, and as they are deformed I guess you could say Grounder's brains are affected by the shape, meaning they have a low intelligence.

I guess we can see this wednesday though.
