It has to do with electron orbitals. When a current is run through the gas the electrons change energy levels, or orbitals, which gives off different colors of light which are unique to that element

All elements emit colors when an electric current is applied.
A flourescent lamp is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light. This light then causes a phosphor to fluoresce, producing visible light.

As a sign (for beer).
When electricity passes through neon gas, it excites the neon atoms, causing them to emit photons of light. This produces the characteristic bright glow that neon is known for.
In a neon light, the light is given off when electricity passes through the neon gas inside the tube. The electricity excites the neon atoms, causing them to emit light as they return to their stable state. This process is what creates the brightly colored glow of a neon light.
Neon gas produces red light when electrified. When an electric current passes through neon gas, it causes the atoms to become excited and emit red light as they return to their normal energy state.
Neon!
An electric current passes through the neon gas inside a neon light, ionizing the gas and causing it to emit light. This process excites the neon atoms, causing them to release photons and produce the characteristic colored glow of the neon light.
Sodium vapor lamps emit yellow light due to the excitation of sodium atoms in the lamp, which produce a characteristic yellow spectrum. Neon lights emit red light because they contain neon gas, which emits light when electricity is applied, resulting in a red color due to the specific wavelength of light emitted by neon.
Neon lights emit a warm, reddish-orange light due to the gas they contain. The light is created when electricity passes through the neon gas, causing it to ionize and emit photons.
Neon emits colored light when an electrical current passes through it, causing the electrons in the neon atoms to become excited and jump to higher energy levels. When the electrons return to their original energy levels, they release energy in the form of light, producing the characteristic bright red-orange glow of neon lights.
Balls
When neon gas is mixed with zinc vapor, the resulting glow is due to the excitation of electrons in the neon atoms. Although zinc itself does not emit light when mixed with neon, it can enhance the brightness of the neon glow due to energy transfer processes. This phenomenon is utilized in some types of neon signs and lighting.
Photosynthesis
Electrons combining with gaseous metal vapor produce a type of light known as atomic emission spectrum. This is the characteristic pattern of specific wavelengths of light emitted by electrons transitioning from high energy states to lower energy states in the atoms of the metal vapor.
