What is the color of the sun? And it really is white

If I asked anyone about the color of the sun, he would not hesitate to answer that it is yellow, but is this answer correct? Please do not go to check the matter with your naked eyes so as not to harm them. They look just a little yellow, especially if we look at them after sunrise or just before sunset, but nevertheless you should not be fooled. If you could go to space and look at the sun without losing your gaze, you would find the sun white, not yellow. With a glass prism, you can 

see how sunlight breaks down into its colors: red, orange, yellow, green, blue, indigo and violet. And when you mix these colors together, you get the white color. Here lies the strangeness of the matter, as our sun appears to us yellow due to the atmosphere. If you look at the coming photons, you will find that our star sends more photons within the green part of the spectrum, and the photons in the upper part of the spectrum, i.e. in blue, indigo and violet, are probably scattered 

far away, unlike the photons in the lower part of the spectrum, i.e. in red Orange and yellow, which are less scattered. When the sun is close to the horizon, you see it further distorted by the Earth's atmosphere, which scatters blue photons away and makes them appear red, and when there is smoke and pollution in the air, this enhances the effect, and will appear redder. But if the 

sun is high in the sky, where there is less interference with the atmosphere, it will look more blue. It is very common for all of us to have a yellowish orange sun, and astronomers will change their color to make their images look yellowish. But the sun really looks like a pure white ball, especially when viewed from outer space. Interestingly, the color of the sun is very important to astronomers. They use a technique called spectroscopy to separate the components of the light spectrum from a star.

 Where the black lines in this spectrum tell you what the star is actually forming, you can also see which stars have large amounts of minerals, and those that are mostly composed of helium and hydrogen, and which are leftovers from the Big Bang. This color also gives us information about the star's temperature. Cold stars are redder, like Betelgeuse, whose temperature does not exceed 3500 Kelvin only. Hot stars, like the star of Gemini (Rigel), may exceed 10,000 K, and look blue. Our sun is about 5,800 K, and when you see it outside our atmosphere, it appears white.
