Ambient Lighting & Its Effects On Eye Colors - Or What Color ARE Tom Hiddleston's Eyes?!
Whenever there are Tom Hiddleston fans, there is always confusion about the man's real eye color, and whether or not he was wearing contact lenses. Are his eyes blue or green? Was he wearing contact lenses part of the time?
As near as I can tell, Tom Hiddleston's eyes are most probably blue-green. Depending on the ambient lighting, blue-green eyes can appear blue or green - and if you pay attention to the photos, they always look green when there's a yellow tint and blue when there's a bluish tint.
To demonstrate how this works, I took some photos of my own eye so you can see just what ambient lighting can do to eye colors like that. Observe:
The first picture is taken in cool light, which makes the iris look blue - even almost gray. The second picture is taken in neutral light, which makes it pretty close to the actual color. The third picture is taken in warm light, so it appears green.
Remember when Loki's eyes looked green? That was when he was in the palace of Asgard, which had a golden cast to it. It probably wasn't that they "forgot" to give him contact lenses in other scenes; most likely it just the differences in lighting.
So whenever you're trying to determine someone's eye color in the future, remember to take ambient lighting into account.
Addendum: I have been told that at some point Tom Hiddleston actually said something about the color of the eyes being manipulated. However, I have never been able to locate the exact quote. My suspicion is that if he did indeed say this, he may have been talking about the promotional poster with Loki, which definitely were manipulated.
Addendum 2: More on the topic of Loki, many fans agree that Loki's eyes were totally green in the scene where Thor nabbed him at Stark Tower and got a knife in the side for his troubles. Still, no cigar. Here are the irises of Loki's eyes from that scene transposed over his cape in the same scene. (His cape, being unequivocally green, makes a good reference.)
This is actually a very good scene to refer to because the lighting here is pretty natural - no tinting effects, no special light colors. And here it's really visible that if you compare Loki's "green" eyes to something that's actually green, they don't quite make the emerald cut. "Okay, but the Tesseract futzes with peoples' eyes!" I can hear some of you saying. Let me reiterate: this is the scene where many fans agree his eyes are green. Plus, people taken over by the Tesseract have their pupils clouded over, whereas Loki's are clearly visible.
But if that's still too ambiguous for you, here are Loki's eyes after he's been Hulk-smashed (at which point, allegedly, the scepter's control wore off) transposed with green from his clothing from the same screenshot.
Finally, compare with someone who does have green eyes in this movie - Scarlett Johansson/Natasha Romanoff. Let's put her eyes through the same tests we've put Tom Hiddleston/Loki's.
See the difference? Now that's what I'm talking about. These right here are some green peepers. But on the odd chance you're still not convinced, here's a comparison of Loki/Hiddleston's and Romanoff/Johansson's eyes next to each other.
Hiddleston/Loki's eyes are greenish, yes. But they're a few alleles short of a proper green.
