You've heard this about the sky. You're WRONG!

Picture this - have you ever seen a blue sea underneath grey skies? Exactly. The sea may not be as bright a blue colour, because less light is reflected off the clouds. It's actually still blue, rather than pure grey or white. Go scuba diving on a cloudy day and see for yourself.

The sea is blue because of the molecules in it, the same reason why the sky is blue. But look up that question...
