The Sun act like a sunlight filter, so the Ocean is blue because water absorbs the red part of the light spectrum. Like a filter this leaves the behind colors in the blue light spectrum for us to visualize. Floating sediments will give off others colors of red, green and other hues and always the white sparkles of reflections from the sun bouncing off surfs.
According to NOAA.gov, Most of the ocean, however, is completely dark. Hardly any light penetrates deeper than 656 feet, and no light penetrates deeper than 3,280 feet.
