I understand that the sky is blue due to rayleigh scattering, but I read that the sky looks red at sunset because the light passes through more air. Does that mean, then, that an atmosphere ten times thicker would give a red sky? Or would it get paler and paler blue (since if you are high up and in thin atmosphere you go from black sky to dark blue sky to light blue sky)? If not any of these colours, then what would happen?
