I am aware, the sun doesn’t look green. But, don’t forget the sky looks blue and we all know it’s not actually blue. The sky seems to be blue for the same reason some people’s eyes look blue, it is due to an optical illusion known as the Tyndall effect.
When scientists evaluate the wavelength (color) of the sun, the optimum output is in the transition area in between blue and green (about 500 nanometers). So, theoretically, the sun is green-blue. But, why doesn’t it look green?
It doesn’t look green due to the fact it also releases light at other wavelengths, plenty of that our eyes mixing these wavelengths with each other perceive the combination as white light. For the reason that of the way our eyes work, we could only see a green star (such as the sun) if its photons are restricted to the green range. Thus, you’ll never actually see a green star (as green).
