Yes, but not the same way as this. The atmosphere scatters light and the higher energy light waves in the blue are of the spectrum scatter more, so the sky appears blue to us.
In this Nebula the gases are excited by the stars in the gas clouds and emit light. They called emission nebulae. They have others that are called reflection nebulae and they are usually gas clouds that have a star(s) that are between us and the cloud, so the light is reflected towards us.
Is it really just gas that colors the sky? This is amazing
