Well, pure water is not blue in colour.
Its transparent essentially, meaning that it has no general colour as such.
Ocean water appears blue because of the way in which light scatters in the water.
Deep see would be more blackish blue because of the absence of light.
Anyway that is actually not the interesting part, the interesting part is how come the sky and the ocean both scatter light in the same way so as to appear blue. Both are in different forms and there are a lot of different characteristics. Is may be one of the reasons why it was believed in early ages that ether may be present in space.
By this logic it would seem that ether having properties similar to water would scatter light which then pass through the transparent sky and it would seem blue to us.
I wonder if this was one of the reasons. Who knows?
