Fairly positive Loki's eye colour was a stylistic choice from Thor they chose not to care much about, just like his beautiful perfectly formed eyebrows. Bruce/the Hulk contradict what was told in TIH concerning his transformation, and that's even a bigger issue. Which sucks, eye colour wise, but as far as I am concerned, his eyes are green and will always be green. Comics and most movie canon supports it and it just looks better.
yes, a good and valid point.
(doesn’t stop us from bitching about it tho whoops)
