The sunlight produces visual effects and a blue sky.

Blue sky.- The colors in the sky (as well as the colors of the rainbow or the Boreal Aurora) are the result of an interaction between the sun and different factors found in the atmosphere, such as dust and humidity.
When these factors enter in contact with the sunlight, they produce a series of visual effects and a wide range of different colors.
In the sunny days, the rays of the sun disperse and those short-wave colors, like blue, are more dominant and disperse better through air humidity than those long-wave colors, like red, obtaining a visual effect that makes the human eye see a completely blue sky.
The reality is that humans are just seeing the sunlight.
