Okay what if Young Xehanort has yellow eyes and pointed ears is because when he leaves his world he grows up and succumbs to darkness to become a darkling. He wears gloves to hide his red hands and he takes Luxu's keyblade because he no longer can wield his own. Puts his heart in his younger self and thats why we see Young Xehanort with yellow eyes and pointed ears. His original eye color was that gray color.
Side Note: It would explain Aquas predicament. She might be succumbing to the Darkness and the result is red hands combo'd with gray/whitening of the hair.
