If the moon was purple what colour would the sun be?

Question

Think if instead of white the moon would be purple!

Based if this considering the sun gives the moon its light and the moon sometimes appears orange like the sun in turn what colour would the sun itself be?

Answer 1

The orangish color of the Moon doesn't come from the Sun's reflected light, but rather from Rayleigh scattering within the Earth's atmosphere [and the Sun's orange or red colors at sunrise and sunset come from the same Rayleigh scattering]. Also, although the Moon generally appears white, it is grey in color and has a low albedo (reflectivity) only reflecting 12% of the light that hits it. It appears bright to us because of its proximity to us, our proximity to the Sun, and the brightness of the Sun. Lastly, star color comes from blackbody radiation (things so hot they begin to glow on their own) and are therefore giving off white light and so their color doesn't really affect the objects they shine on.
