Oddly, the sky actually is purple in a certain sense. All of the physics that explains how the blue wavelengths of sunlight are scattered more strongly than colors at the red end of the visible spectrum (resulting in a blue sky) goes even more for violet wavelengths. It’s just that our eyes are more sensitive to blue wavelengths than to violet ones.

That’s not what the English word purple means. *rolls eyes*
