Is the blue sky really blue?

In fact, the sky is not blue. The sky is actually a mixed color, which is formed by the scattering of sunlight. In fact, the sun has seven colors, which are red, orange, yellow, green, blue and purple. The blue is easily absorbed by the atmosphere, and then reflected by various molecules in the atmosphere, forming the blue in the sky!
