Hello. Thank you for using Petco Pet Education Center, formerly Petcoach. Great question! Hades is very handsome! It takes about 10- 12 weeks for a puppy's eye color to become permanent but it can take as long as 16 weeks. Since Hades is almost 20 weeks of age I would say his current eye color is going to be his permanent color. There are many dogs with dark coat colors that have light eyes. This is not uncommon. Hope this answers your question. Best wishes!
