Blue is my favorite color. What is yours?
That's crazy, blue is my favorite color as well!
I think it is a vorite of many considering it was even used in ancient Egypt for jewelry and ornaments. In facts, the most expensive pigment during the Renaissance was made of the color blue.
That's fascinating, I had no idea. I think it is a perfect mix of darker shades but can also be incredibly vibrant. There are a ton of different combinations of other colors it goes extremely well with, especially white and mixes of lighter/darker shades of blue for contrast.
Saying blue is pretty vague when you consider the many different shades like azure or ultramarine which actually include bits of other colors. 
Right. What is your favorite shade? I prefer a darker navy blue, or a vibrant sea blue. I am not very partial when it comes to the lighter sky/baby blues, but when mixed with darker shades in different aspects of design, it can look fantastic.
I like sky blue, even though the sky actually only appears blue because of the Rayleigh scattering effect.
That's very interesting. does it relate to the way the human eye interprets the rays of light from the color? I like the dark steel blue that the sky can get during inclement weather which casts a gorgeous mix of the color to the environment on the surface, such as grass, trees and a clean street.
