hello, my favorite color is blue
So is mine!  Blues typically contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.  And blue is so pretty!
i agree, blue is such a appealing color
I love when the sky is blue, which is because of an optical effect known as Rayleigh scattering
I always wonder why the sky is blue
The Rayleigh scattering is also the reason that the sea looks blue!
never thought there was a reason I just assume it was just blue
It's a good thing I like blue, because I have blue eyes!  That's caused by an optical effect called Tyndall scattering 
so without the scattering what color would it be otherwise?
Gosh, I don't know!  But I do know that blue has been considered an important color in both art and decoration since the ancient times!
