What is the color of the sky?

Agotha, I live in Colorado and because of the high altitude and low humidity, we have beautiful deep blue skies. No ocean for miles and miles! 🙂

Amazing. I had read somewhere the blue was a reflection of the ocean, but I'm not entirely sure of it. Fun query!

Agotha, no, nothing to do with the ocean. Entirely related to the shorter wavelength of blue light causing more blue photons to be bounced about (backscattered) by the atoms in the atmosphere.

Confusing explanation. The scattering that occurs to produce the blue color is done by the gasses in the sky. It's like saying that blood isn't red, it just looks red because it's reflecting red light.

An odd answer. You could give the same answer about anything. Everything could be colourless but because it scatters or reflects light of certain wavelengths it "appears" to be a certain colour. Surely the sky's colour is what it "appears" to be. This is usually blue because the higher frequency parts of the light from the sun (going towards violet or blue) are scattered more strongly (Raleigh Scattering). However it now appears everything is colourless. I will therefore take my colourless self elsewhere.

the sky appears blue due to Riemann scattering which is much stronger in the blue end of the spectrum.

Agotha, just the reflection of light passing through gases

Agotha, heard that too
