Your theory is that eye color is important in chosing a maiden, right?

Ozpin said that the rules are: last thoughts of a dying maide, has to be female and has to be fairly young.

He did not mention anything else. So either your theory is wrong, or Ozpin is a liar. And since the person giving important exposition should not be a liar as it would break the show the only other answer is that you are wrong.
