I don't think color of antlers have anything to do with age. I live in Mt. and deer here deerlive in diff. areas and have diff. color antlers. Muleys that live in the ceder will have dark antlers because they rub on ceder and they get sticky and collect dirt. The deer that live in open country will have light colored antlers. I have seen deer with no teeth and have light colored antlers. This is just my opinion.
