Anyways, just wanted to say that. In season 10 of Red vs. Blue  the fact that Carolina had the same color eyes as the Director and the fact that she didn't like good byes was used to hint that she was the Director's and Alison's daughter. So rooster teeth does use unique eye colors to show relationships
