The color of the Sun can be white, yellow or orange. Out in space, it will always be white. Down on Earth, Sun's light is scattered in the atmosphere. The short waves (blue) more so than the long waves [1]. The end result is that the sky looks blue and the Sun looks like the complement of the sky. At midday, the light from the Sun comes in the most direct way, so there is little scattering, and we perceive the sky as less blue and the Sun a very bright yellow. At sunset, the rays go through a much thicker layer of atmosphere, there's a lot of scattering going on, and you end up with a dark color of the sky (blue-purple) and an orange tending to red Sun. Whoever says the color of the Sun is always white has no idea what they are talking about. [1] https://en.wikipedia.org/wiki/Rayleigh_scattering https://en.wikipedia.org/wiki/Rayleigh_scattering
