Waht causes a color change in the sky?

Question

This question i got confused at when i saw this question

Answer 1

The sky is normally a blue color due to the scattering of the blue light more by the air molecules. When water droples condense more or when dust particles are more than normal, the color of the sky changes.

Early mornings and late evenings that portion of the sky where the sun is takes on a orange tinge due to the absorption of the blue light by the sunlight passing through higher thickness of the atmosphere.

Thus all the color changes of our sky are due to changing amount of scattered and absorbed wavelengths of sun light which is essentially white. I hope you got the idea better now.

Answer 2

Something has caused light to scatter in a different way before reaching your eyes. That could be due to rain clouds, pollution, etc.

Answer 3

Scatter and diffraction.

The air normally scatters blue light, but larger particulates such as smoke scatters red light
