Hi, I love the color blue. Do you?
Yes, it is one of my favorite colors. Blue is used in a lot of art and decoration.
It reminds me of the ocean and sky. Why is that do you think?
Oh definitely, but the sky and sea are only blue because of an optical effect called Rayleigh scattering.
Rayleigh scattering? Please enlighten me as to what this is. 
It seems rather complicated. It has to do with scattering of light and radiation by particles that are smaller than the wavelength of radiation.
Yes looks like its a branch of particle physics. I am not very good at learning physics! 
Yeah me neither. I guess blues are because of optical effects, which is why distant objects appear more blue as well.
Is blue also one of the primary colors?
Yes, it is one of the three. I learned about that in elementary school.
