neon signs employ neon in only one color: red. other gases are used in other colors. Neon was not even descovered as the first color in neon. it was mercury (blue).
i got this interpretation from this site:

They work by applying pressure to neon gas. That is what makes them luminesce.
And yes other gasses make different colours. But neon was the first gas used in commercial signs. Besides, I guess 'argon signs' just didn't sound that great!

Neon is the gas that when electricity passes through causes the sign to light up.

my teacher last year did this experiment where she had like this chamber/light looking thing where when she flipped the switch a gas was released [in a secluded chamber] depending on what gas it was ... it had a different light. I don't know why its called Neon Light but maybe it has the element of Neon in it! good luck.
