I like the color blue. 
It truly is a solid color. In fact, it's one of the three primary colors of pigments that are used in painting and traditional color theory. Even in the RGB color model! So, it provides a lot of foundation to our world.
Really how so?
Well, take the daytime sky and the deep sea, for instance. These things appear blue, but it's actually an optical effect called the Rayleigh scattering. But in essence, there are many "blue" things in our world.
