Yes, the pink inside the mouth is a mistake--in areas like that where the blood vessels lie close to the skin surface, the color you see is actually the blood. So to be scientifically correct, the inside of a Pred's mouth would be glow-in-the-dark green.

Thats why they wear bio masks! haha.scanff said:Nah, I think it was the right thing to keep the mouth red. As a silent hunter the last thing you'd want is a glowing green mouth, especially at night ;p.
I agree Scanff, this make perfect sense from an evolutionary standpoint. If not pink, as is the color of our mouths, the Predator's color could have been made a muddled brown. ( green and pink make brown) I'm of the opinion that the majority of creatures resideing on the predator home would have glowing green blood, just as the majority here have red. I've always had it figured that the green glowing blood served as a type of signal to other predatory/flesh eating species that there was a wounded creature..i.e possible meal near by, and would enable them to close in on it rather quickly.scanff said:Nah, I think it was the right thing to keep the mouth red.
