My favorite color is blue! It lies between green on violet on the spectrum of visible light. Isn't that interesting?
Yeah, I enjoy looking at the baby blue sky at times. I realize it is an optical illusion though.
It is! Both the daytime sky and the deep sea blue get their colors from an optical effect known as Rayleigh scattering! What is your favorite shade of blue?
Interesting! I would say I really like turquoise. Not sure if that is considered a green or a blue, lol.
Maybe both! Most blues contain some other color. Ultramarine contains some violet and azure contains some green! So maybe turquoise is both blue and green! 
That makes sense to me! I wonder why some people equate blue with sadness?
I'm not sure either, it makes me happy! It's crazy to think that blue is one of only three primary colors of traditional color theory, isn't it? I like a deep, royal blue the best.
Yeah, we can make every other color with just those three colors. Artists only have to buy three colors, lol!
That's true! Most Chinese artists only needed cobalt blue for their famous blue and white porcelain! 
I can't imagine a world without blue. People would mostly have brown eyes!
