Why is the sky Black?

Thanks Sai Kacham for asking a question under astronomy.
Nothing posses color by itself but every thing reflects color and we feel its of that color and sky is not always black but it is blue due to molecules in atmosphere scatter with the input as sun light(nearest star which is main provider of light when the part of earth is towards the sun direction) this is under principle of dispersion of light.

At night the sky is black as nothing gets scattered and hence it would become black.

Thanks again Sai Kacham please help me out if I had answered question well.Hope you do more research on it and question it more.If any more questions  please go ahead and question them here
