Yes, I know that, the thing is that this drawing goes with an article written by another person and she says his eyes are 2 different colors (she repeats it in several occasions), so I just wanted to match the text... but I know his eyes are both blue, just one of them looks darker due to the dilated pupil.
aah... that would explain it then. I used to think they were two different colors when I first saw him. I actually met a girl who had one blue eye and one brown eye. It was very startling and eye catching.
