My favourite colour is blue! :)
You aren't the only one who likes blue, it has been used in all sorts of art since ancient times.
Yeah I love the way it looks, especially the ocean blue colours. 
Natures blues, such as clear daytime, or even the deep ocean only appear blue due to Rayleigh scattering.Which is a fancy way of saying optical effect.
Wow that is pretty cool! What else do you know about this colour?
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
in 2006, it was given an English dub produced by Ocean Productions and recorded at Blue Water Studios.
