Great White Sharks, as well as most oceanic fish, have a structural adaptation which is known as counter-shading. The dorsal (top) side of the shark grey so that it blends in with the ocean floor making it hard to be seen form above, allowing the shark to sneak up on its prey from below. The ventral (underside) side of the shark is white so that it blends in with the uppermost layer of the water (which appears white from below) making it hard to be seen from below. This acts as both a defensive mechanism as well as a predatory advantage for Great Whites. They blend in with the surface of the water therefore making it hard to be noticed by both its prey and its predators.
