Chlorine gas is green.
If you heat iodine to make iodine gas it is a beautiful purple.
Gasses of several compounds are also visible.
It depends on what gas you are talking about.
Gas is only visible by having a certain color: Chlorine: greenish yellow, Iodine: purple, Bromine: redish brown. No color, not visible.
oxygen i s colorless gas because it does not appear in the visible region of uv visible spectroscopy
Carbon dioxide in its Gaseous form is not visible.
CO is a gas. It has no color

I think you are looking for the Photosphere. That is the part of a star that emits visible light.
The temperature of the layer of gas that produces the visible light of the Sun is around 5,500 degrees Celsius (9,932 degrees Fahrenheit). This layer is called the photosphere and is the visible surface of the Sun. It emits light in the visible spectrum that we see.
Certainly; you can see the light that it gives off.
The visible cloud of dust and gas in space is called a nebula. Nebulas are often regions where new stars are forming, and they can vary in size, shape, and color.
A gas hookup will have fittings for a gas line, they should be clearly visible. In an electric hookup there will be an electrical plug, but no gas lines showing.
No, they should be underneath.
