One of the best-known visible gases would be Chlorine. Chlorine shows as a putrid green-yellow cloud, and is incredibly toxic to humans.
Usually it seems that they are. Some really are. Others are just not presented in a way that makes them visible. In short, some gases are visible and have colors. Check the link.
No.Sometimes farts are just gas so they do not always smell.
Noble gases are generally considered to be transparent to visible light because they do not absorb or emit light in this spectrum. This transparency is due to their full outer electron shells, which make them chemically inert and less likely to interact with photons. However, under specific conditions, such as at high pressures or in certain plasma states, noble gases can exhibit some absorption of light. Overall, in their standard gaseous state, they are largely transparent.
I can only tell you that gases are does not have a difinite shape and volume . E.g air / nitrogen / carbon dioxide / water vapour / . . .
Some scientists that studies the behavior of gases include Niels Bohr, Antoine Lavoisier, and John Rayleigh. ChaCha on!
Excepting some colorless gases all chemical elements are visible.

Most gases are invisible to the naked eye. Gases are made up of molecules that are spread out and don't absorb or reflect light in a way that makes them visible. However, some gases do have odors that can be detected.
they not only contain H2 and helium.they also contain dust particles,gases & some asteroids which make them visible. R.S.SRIRAMGOPAL
Greenhouse gases interact with visible light by allowing it to pass through the Earth's atmosphere. When sunlight reaches the Earth's surface, it is absorbed and then re-emitted as infrared radiation. Greenhouse gases trap some of this infrared radiation, preventing it from escaping back into space and leading to the warming of the Earth's surface.
Gas has the same shape as its container fills. But some gases are visible.

Common gases in a house that may be visible include smoke (carbon particles), steam (water vapor), and possibly dust particles in the air. Other invisible gases like carbon dioxide, methane, and natural gas may also be present but not visible to the naked eye.

The corona.
The gasses that make up the sun's corona.
It's mostly to do with density. In simple terms, gases have very low densities compared to solids and liquids, so that their molecules/atoms cause very little scatting of light as it passes through them.
