What were the physical characteristics of the greek god Poseidon?

sources are all different but most of the ones that add up say that he had sea-green eyes that changed to storm gray when he was angry. His hair was wavy brown or brown with streaks of gray and he had the body of a long time swimmer think Michael phelps umm he also had a short beard and that was streaked to he had laugh lines around his eyes and he was very tanned thats about it now of course sum credit him with a potbelly or greenish blue skin but yea that i think would be closer to wat he originally was intended to look like
