Typically, color does not show us very much interesting about the character. OK, so your character has green eyes instead of blue or brown. So what? Try to focus on details that capture the characters choices and lifestyle. For example, instead of focusing on his hair-color (which he has no control over), mention the way he wears his hair. That suggests something about his attitude and environment. Also, his tight suit and geeky glasses and smile suggest something about his job, mood and education. If we gave him a Rush t-shirt instead and a sloppy haircut, hed look like a much different character.
