"it's actually the light being refracted by our atmosphere"
Actually it's because the blue color is a result of Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
Or, it is what you said! LOL Couldn't resist my friend! Hope things are good this time of year! Now, can you explain to me the chicken on the June Bug concept?
Good luck to you, me, us, and all longs.
