Which of the following gases are typically used for colorful lighting when an electric current is apllied

Neon is by far the most common gas used ... the reason why these displays are called "neon signs". Argon is also often used as the main component. Xenon, Krypton, and Helium are often added for special color effects, but are never used alone without neon or argon.

Well i really need to see the choices but i think you mean neon
