Why is the sky blue?

Asked by Patty_Melt (17513points) October 9th, 2017

So, I know about different colors of light, refraction, and stuff like that, BUT, what would have to change so that instead of blue, on clear days the sky would be purple?
Could it happen if there were a change of gas content in the atmosphere? Atmospheric depth?
Would it require a different sort of sun?
