Black. Because if his hat were white, since there are only 2 white hats then one of the people behind him would have known the color of their own hat based on what they saw and/or the previous person's answer. If the front 2 both had white hats, both the last 2 would have know what color hat they wore. If only the front person had on a white hat, the last person would still not know and that would let him know that his hat was not white, so he would have also known the color of his hat. The only other scenarios involve the front person having a black hat, so since neither knew their own hat color, his has to be black
