: Actually no. And a google image search for Liquid Oxygen doesn't give an image I'm totally convinced is actually of Oxygen (Best match seems to be a flask of Ozone, although it is most certainly a very deep blue). | : Actually no.

What is happening with the sky is that air can appear to glow with various colors when illuminated with a strong directional source of light, such as the sun. The color depends on multiple factors, including the angle of illumination and observation. The glow can be commonly seen being blue, white, yellow, or red - with blue hues generally observable on clear days, and reddish hues at sunrise or sunset. This only works with a directional source of light; when the source of light is diffuse, such as under a large cloud cover, the sky doesn't appear blue, and neither do distant mountains, readily disproving the notion that air itself would be blue. | What is happening with the sky is that air can appear to glow with various colors when illuminated with a strong directional source of light, such as the sun.
