Not only this but in the Thor movies lokis eyes are clearly green but in avengers they look blue we can see with hawkeye and others that your eyes turn blue under the control of the scepter - Loki Theory
I wish they did something like this in the movie! Loki's only hiding his Jotun form. So if he were to die, naturally his magic used to hide his form would deplete and his natural blue form would arise, right? <-- Oh Loki.
Wolf Pearlescent, by Lhuin. A beautiful example of how an image based on a white subject doesn't have to be monochrome.
Frost giant Loki! I did not realize how much I wanted this! I really want Loki to figure out that he has some awesome frost giant powers in avengers infinity war! And his eyes turn red when he uses them and sometimes his skin turns blue for a short while when he uses a lot of power. that would be amazing!!!!
