What colour is the Terminator's cybernetic eye?

i've partially forgot about it but i've seen part of the Terminator on television

The Terminator franchise is one the best and most successful franchises in movie history. When the first film came out, it was one the best edge-of-your seat; pulse-pounding movies. It still has a lot of that effect even in today’s times.

Marcy, All of the Terminator movies r awesome w/special effects and all, I just wish the language wasn't so foul. Very interesting plot though.

Marcy, on the picture you see grey but it’s red that’s so much funny

Marcy, cool
