I stand corrected.

Yes I must correct myself, I kinda knew it when I wrote it... but didn't pay
much attention to it.

It's like this:

Green is for spotting cloacked predators. (Predators are then white)
Blue is for spotting the body heat of human beings. (Environment is blue,
humans heat up)
Red is for spotting aliens and their acid blood or so (Aliens lit up
green or something)

Euhm there seems to be something new in this movie ?

Yellowish ?

Strange
