$\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}$

⭐Actually Welcome to the Concept of the Dispersion of Light

⭐Now basically when see the phenomenon of the Dispersion of light, the white light after passing through a prism like material splits into VIBGYOR, I. e. seven different colours.

⭐So when the White light in the form of radiation passes from the atmospheric layers of the earth which act as different opticals layers of different refractive indices.

⭐The light splits and thus we are able to see the objects and sky around us as colourful.

⭐But if there is no light falling on the earth from the sun, then there is no splitting of light and thus the Sky will appear as total black like the space.
