The "Sun" experts ... let me guess, they're on page 2 of the Sun.
They must be the same sort of "scientific experts" who claim that the world is cooling off.
Ask a Physicist about atoms emitting signature Spectra. There is one huge shit-pile of hydrogen up there, heated to unimaginably hot temperatures where their electrons merrily leap up-and-down and emit vast amounts of yellow light.
What is the Actual Color of The Sun?
The real color of the sun is white. The reason that the Sun looks yellow to us is because the Earth’s atmosphere scatters higher wavelength colors, like red, orange and yellow less easily. Hence, these wavelengths are what we see, which is why the Sun appears yellow.
As a child, you almost certainly drew the Sun in the shape of a face on your notebook, and invariably, the color of the Sun’s face would have been yellow. If you had been a fan of sunsets and sunrises, however, then the color of your Sun’s face would have been orange or red.
However, you might be surprised to know that the Sun is not orange, yellow, or anything in between. In fact, the color of the Sun is WHITE!
