Why gases are colorless?

Answer 1

Some are not.

The gasses (and anything else for that matter) that are colorless are so because none of the constituent atoms or molecules have electron orbits with energy gaps that correspond to the energies of wavelengths of light that we see.

Answer 2

Gases are colorless because they do not absorb light in the visible spectrum. This means that they do not reflect or emit any particular color, which results in them appearing colorless to the human eye.
