Your pupils dilate when you hear or see something you like, and contract when you see something you dislike. It's literally a second rudimentary set of eyebrows you can't control. Imagine a blonde girl smiling up at you, pupils all big like a puppy. She likes you doesn't she? Now hold that same face in your mind but shrink the pupils. Is she thinking of cutting your dick off while you sleep? Maybe. Maybe your breath stinks. In any case there absolutely IS a difference between light and dark eyes.
