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.

Why does a white ring form when ammonia and hydrochloric acid diffuse?
Both ammonia and hydrochloric acid are colorless gases at standard temperature and pressure, but they are capable of reacting with each other to produce ammonium chloride, which is a white solid at standard temperature and pressure. Colorless gases are invisible to human eyes, but white solids are not. When the two gases diffuse toward one another, they form finely divided white solids that remain visible for a while as a white ring in the diffusion interface.
