Why does the sky changes color? can you explain me how it works? < 3

There are many proximate causes for changes to the color of the sky, but they all involve the way light is diffracted through the air. Light from the sun can be bent as it moves through the Earth's atmosphere, and the wavelengths of light that are able to pass most easily through the air give the sky its color.
