The sunset or the swastamita is the time when the sun disappears below the horizon line to the west. The red color in the sky at sunset and rising is caused by a combination of blue Rayleigh spreading and density of Earth's atmosphere.

A natural phenomenon called Rayleigh scatter plays a major role in this. The phenomenon causes sunlight to bounce off tiny particles in the atmosphere and scatter in all directions.

Sunlight consists of various colors, including red that has the longest wave of all colors. The color of light that is able to reach humans is a color that has a longer beam of light that is red.

Colors red, orange, and yellow can reach the human eye without having to splatter in space. The three colors become the reason why the sun looks red at that time.
