I think, technically speaking due to Rayleigh Scattering and the nature of our sun, the sky wouldn’t be blue if it weren’t for the composition of our atmosphere — if I’m remembering correctly. So the sky could potentially be a different color with a different atmosphere, or at least we would perceive it that way (we are also sensitive to the color blue, so it is easier to see).
Idk, this has led to many more questions than I anticipated. I guess if you’re very strict about the light not being a part of the atmosphere due to scattering then it is not blue. Other factors like clouds, fog, smog, obviously play a part.
Well, the sky isn’t objectively blue, it just appears so to us.
Isn’t that everything?
