"Uhm acktually, the sky is not blue, it's clear. It just appears blue because the blue light is scattered more than other colours, as it travels as shorter, smaller waves." ☝
like gang, I get it. I learned that in like 3rd or 4th grade gang. To me, if the sky looks blue, it's blue. If you wanna get technical, nothing actually has colour as colour is not an inherent property of objects but a perception created by the brain when it interprets light wavelengths reflected off surfaces. We only perceive colour but it doesn't truly exist, so nothing is blue at all.
