Suppose you are on another planet which has an atmosphere.  Will the skies be blue?

Rayleigh scattering is a function of the chemical composition of the atmosphere as well as the density profile.

 

Every planet has an atmosphere.  Even Mercury has an atmosphere (not much of one, a trillionth of ours perhaps.)

 

Venus has an atmosphere, but skies there are white if you are high enough, probably nearly black from down at the surface.

 

If a planet has an atmosphere like ours with a gravitational field like ours and is a similar distance from a star like ours, good chance that planet would have blue skies.
