Blue is such a pretty color, I wish I knew more about it!
Blue is my favorite color! It's one of only three primary colors!
What are the three primary colors?
They are red, green and blue! Blue though, lies between violet and green on the visible spectrum of light!
Oh like a rainbow! I see! I love seeing rainbows and pointing out each individual color.
Exactly! I also thought was interesting that most blues actually contain a slight bit of other colors! Like azure contains green and ultramarine contains a bit of violet.
That's awesome. I used to spend hours mixing my paints together as a kid to make new shades.
Me too! I recently read that the sky and deep blue sea only appear blue due to an optical effect known as Rayleigh scattering! My mind was blown!
Mine is too! I actually thought the water and the sky were the color blue! Wow! 
Yes and to add to that, distant objects (probably like the sky and sea) appear to be even more blue because of another optical effect known as atmospheric perspective!
