You may be referring to the Noble Gases, but they certainly are not inert as there have been several Noble Gas compounds made. The Noble Gases refer to group 18 of the Periodic Table. All of the gases are colorless, tasteless, and odorless in their native form and under standard conditions. However, when electricity is passed through them within a gas discharge tube the gas particles give off light. In gas discharge tubes, a current will disassociate electrons from the gas molecules, creating ions, and when electrons recombine with the ions, different lighting effects are created. The light will be characteristic of the material contained within the tube and will be composed of one or more narrow spectral lines. In this case:
- Helium: Light yellow to orange.
- Neon: Reddish-orange.
- Argon: Purple to pale lavender blue.
- Krypton: Lime green. At high peak currents, bright blue-white.
- Xenon: Turquoise light blue. At high peak currents, very bright green-blue.
- Radon: Deep red. Not used as a luminescent gas due to radioactivity.

What is a spectral signature?
A spectral pattern is basically a line of dark or bright colors that continue on and never stop. These patterns and lines can be used to identify gases and lights.
Why clear sky appear blue?
sun's rays are made up of a mixture of seven colors. it is apparent in the rainbow. oxygen and nitrogen occupy not less than 98% of the gases in the air. blue light in the sun's rays are scattered when it hits those gases.
What are the types of toxic gases?
blister gases, choking gases and nerve gases
Which gases are considered monatomic gases?
There are many gases that can be considered monatomic gases. Some of these gases are helium, neon, argon, krypton, xenon and radon and all of those gases are considered noble gases.
Greenhouse gases are -trapping gases?
Heat-trapping gases.
What are the exterior colors of mercury mountaineer?
Because of all the different gases that it has.
Do gases come in different colors?
Many gases are colourless, but not all. Some examples :chlorine - yellowish greenbromine - reddish browniodine - violet
Why is Jupiter white brown orange red and green?
It's multicolored because of the colors of the gases.
Which element is in illuminated signs?
The noble gases are used in illuminated (aka Neon) signs. Refer to the related link to see an illustration of the colors made by the different noble gases.
What kind of gas lights up lights bulbs into various colors?
Nobles gases like argon, neon....
Are all gases invisible?
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.
What gases make up neon colors?
Look to the far right of the periodic table. Those are inert gases. Neon among them. On my chart in the "Life Science Libary" "Matter" book they were in tubes and electrified. They all had unique colors. By mixing them you have a pallet of electric light.
Which gases emit colors when an electric current is applied?
All elements emit colors when an electric current is applied.
Is there a neon white?
Yes, but the gas is carbon dioxide, not neon. Actual neon lights glow red. Different gases glow different colors.

Why are the colors of the spectrum different in each gas?
A spectrum is a function of the light source. A gas will absorb / emit light based on its molecular bonds, and different gases have different bonds.
