I love blue, Blue is one of the three primary colours
It is beautiful. Is the ocean blue or is the sky blue. Which reflects the other? 
It lies between violet and green on the spectrum i think
Yea a mix of color's. Back to the question at hand, the sky or the ocean? 
I think it is blue because of an optical effect known as Rayleigh scattering
Interesting. It's strange the sky is blue but space beyond it is black. We live in a crazy world.
Blue has been an important colour in art and decoration since the start of time
I wonder if it's importance inspired pablo picasso blue period.
