When a penguin is in the water, it swims usually with its belly down, and back up. Its back is black, so that to fish and predators who are above the penguin, the penguin's dark back blends in with the darkness of the depths of the ocean. For fish and predators who view the penguin from below, the penguin's white belly blends in with the brightness of the sky and the water's surface.
