Um... duh?

has no color. It is clear

Are you quizzing us?

but is the sky really blue? or maybe it's a different color. maybe it doesn't even have a color.
i mean, we only see the colors that are reflected off the surface of something. but the sky isn't a surface. so, what color is the sky?

whoa.

The sky is truly colorless we've all been lied to

The light from the sun scatters more blue light than other colours. The blue light in the sky travels shorter than other colour light.
