I love the color blue it is one of the primary colors
Yes, I agree. It is a very bold and vibrant color.
most shades of blue contain other colors mixed in as well
Really? Which ones?
azure contains a small amount of green, and aquamarine has some violet shades within it 
That is really neat how many shades make up on color. 
I am not really sure of that one but Chinese artists use cobalt blue to color fine percelain
