Stray overlay turns dark blue when wearing enchanted armor

When the Stray wears enchanted armor, the overlay turns more dark blue.

Steps to reproduce:

1. Enchant any piece of armor with any enchantment.
2. Spawn a Skeleton.
3. Use this command:

   /entitydata @e[type=Skeleton,c=1] {CanPickUpLoot:1b,SkeletonType:2b}

4. Drop the enchanted armor piece and make the stray pick it up. (Make sure the gamerule mobGriefing is set to true.)
