Why does the sea change colour?

Various reasons i.e. how deep it ,How fast its moving dragging up sediment

The sea rarely changes colour as such - what changes is the light refraction, which can appear to provide patches of different colour. Refraction is affected by th depth of the sea bed, by seaweed and other matter, and by weather changes, all of which can affect the light levels that seem to show the sea as different colours.
