Topic of the day 3/29

Why is the sky blue?

Basically, the color of light, Kelvin, is radiated around and the blue light is absorbed and scattered in every direction, the closer the sky is to you, the bluer it appears, which is why it pales as it nears the horizon line in the distance.


The colors of the sunset are created by dust and water particles in the air reflecting light in all different directions.  Different particles can emit different kinds of light.  And different lengths of wavelengths display brighter or dimmer colors.
