What's the true color of the sky?

As far as wavelengths go, Earth's sky really is a bluish violet. But because of our eyes we see it as pale blue.

Is the sky really blue yes or no?

The sky isn't actually blue and the sun isn't actually yellow — they just appear that way. ... The shorter blue and violet wavelengths get scattered most by the air, making the sky around us appear blue.

Is the sky Purple?

When you look up at the sky, any light that you see has been redirected toward your eyes—it has been scattered. Because you are seeing only scattered light, the sky appears blue. But violet light has an even shorter wavelength and a higher frequency than blue light, so by all accounts the sky light should be violet!

Is the sky really blue or black?

The sunlight reaching our eyes has a high ratio of short, bluish wavelengths compared to medium and long wavelengths, so we perceive the sky as being blue. Without an atmosphere the sky appears black, as evidenced by the lunar sky in pictures taken from the moon. But even a black sky has some lightness.
