I know that Jonas has lighter eyes than others in the community. I need to know more about his physical appearance. I understand that he lives in Sameness, and is similar to other 12-year-olds in the community physically.
Jonas is not described in detail, but we do know that the most important thing about him is that he looks like everyone else other than his eye color. His eyes make him different, but not enough to make him really stand out. That means that in general his other physical traits do not distinguish him. He fits in to the community in terms of appearance.
