What color is the sun?

For most people, the question of what color the sun sounds is meaningless. They will suggest just to look at the sky and make sure that the sun is yellow. However, not everything is as simple as it seems. The star closest to us radiates light in the entire visible range, from red to violet. The human brain combines the emitted colors, with the final color we perceive as yellow. Technically mixing all the colors of the visible spectrum gives white color. This is easily seen by substituting a sheet of white paper under the sunlight. The paper will look exactly white, not yellow.

However, this is not all. Back in 1881, with the help of physical instruments, the American astronomer Langley proved that the maximum solar radiation falls on the blue-green part of the spectrum. If you look at what color the sun shines in deep space - the color of the star will be bright blue.
