Why the colors of the sun varies? interesting facts )))

Sunlight contains all the colors of the rainbow, which are mixed to form white. Because of this, solar light appears white. In the Earth's atmosphere is scattered radiation of certain wavelengths (mostly blue). Therefore, the sunlight seems to us colored. When the sun is high in the sky, it is most scattered blue light. The sky looks blue, and the sun - yellow. At sunrise or sunset when sunlight passes into the Earth's atmosphere over the long way, the sun looks red (red light has the longest wavelength in the visible range).
