Hi there! My favorite color is blue, it's all over my room, and my bedsheets and decorations all have blue in them. 
Oh nice! What is it about blue that you like so much?
Ever since I have been little, it's always been my favorite. There's just something about the color that entrances me...
Well interesting you like it, I was reading the other day and found out that it is one the three primary colours!
It sure is! There's so many shades to blue though, I think that I like navy blue the most. 
I also read that distant objects appear more blue because of another optical effect called atmospheric perspective.
Oh really? I hadn't heard of that, that's pretty cool. Is it the air that causes that effect?
Yes, in fact distant objects appear more blue because of another optical effect called atmospheric perspective.
That's really neat. Blue is actually one of the rarest pigments in nature, it hardly appears on plants and animals. Which is kind of weird, since it's considered a primary color!
fascinating!
I know, right? Well, thanks for your time! Have a good day :)
