response: Yes, it happens due to Rayleigh scattering, which is an optical effect.
original_response: I also like blue, which is the color of the sky and deep sea due to scattering of light.
history: Red is the color of my soul. What color is your soul? I would not know although have you heard that violet is opposite to red on the visible spectrum of light? Never knew that actually, I've always wondered what makes the sky and sea blue though. Do you happen to know anything?
knowledge: The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
