It is basically because of scattering of light in the atmosphere.

Our atmosphere is primarily composed of tiny nitrogen and oxygen particles.

Now usually, when sunlight comprising of seven colors passes through the atmosphere.

It hits the nitrogen and oxygen particles.

These particles scatter blue and violet light
more as compared to red.

Hence, mostly bluish light enters our eyes,
thus making the sky to usually appear blue.

The sunlight must pass through a greater distance in the earth's atmosphere.

Causing it to pass through more particles.

As a result, most of the blue and violet light
get scattered before they reach our eyes.

Due to this, the less scattered light like
red or orange reaches our eyes.
