What is the true color of the sun?

In school we are taught that the sun is yellow, we see it from the earth and we believe that this is its true color, this is not so and we can say that the vast majority of the population is wrong, the true color of the sun does not It is yellow or red, it is white.

Our sun emits electromagnetic radiation over a wide range of wavelengths, but it does so in a greater proportion in the range of 380 to 780 nanometers. That is why the organs of vision of living beings on our planet have evolved to be sensitive to that range, and so we call this area of ​​the electromagnetic spectrum the visible. The short wavelengths, around 400 nm, are what we perceive as violet colors and the long ones, around 700 nm, are what we call reds. Within this area of ​​the visible, the sun emits in all colors more or less equally, so the color of the sun is white, the combination of all colors (it actually emits a little more in the area of ​​greens, But our eyes could not appreciate that difference)

On the other hand, the Earth's atmosphere disperses the shorter wavelengths better, so before reaching our eyes the sunlight has lost more of the colors corresponding to those lengths (violets and blue), and we see it more yellowish or even reddish In the sunsets and sunrises, when the light crosses a greater amount of atmosphere before arriving at our eyes. Incidentally, this also explains the blue color of the daytime sky, since that light has been dispersed to a greater extent by the atmosphere.
