Yes. That's why it's blue on a clear day and gray on a cloudy day. You can also get brown nears estuaries, blue green in shallow areas with sandy bottoms, red in algae blooms, etc.

No, but sky reflection is part of the reason that you see oceans as blue.

Apparently, water tends to absorb more red light...
