Paul Giulan#DidYouKnow the sun is actually white?
It looks yellow because the Earth’s atmosphere scatters blue light more efficiently than red light. This slight deficit in blue light means the eye perceives the colour of the Sun as yellow.
The more atmosphere the Sun’s light passes through, the more blue light is scattered. Hence, during sunrises and sunsets there is a much greater percentage of red light in the Sun’s spectrum, giving often spectacular results.
