It is almost always it is the phospore coating inside the tube. less commonly, it is the actual color of the glass... but colored glass is much more expensive than the phosphore coated type that is clear glass. I love bending up colored glass but most people will not pay for it. It is more popular in Europe than in America.
there are usually only two different gasses used... RED is generated from NEON fill gas and is used for pink, red, and orange colors. Blue gas is generated from ARGON and vaporized Mercury and puts out alot of UV (ultraviolet) energy. This invisible UV light causes rare-earth phosphore powders to glow immensely. If you look closely at the ends of a blue, green, purple, yellow, gold, violet or white neon tube, you will see the electrode ends are clear and glow blue. Sometimes you can see this in a splice where two parts of a neon tube are welded together. That blue gas is the same Argon/mercury gas in most florescent lamps in office buildings, in new spiral-bent energy efficient compact florescent lamps, and even in HID parking lot lights.
that is why it is important that we recycle these lamps properly rather than just throwing them away. We don't need to put this mercury in a concentrated place.
A neon sign produces an emission spectrum, which is characterized by bright, colorful lines of light at specific wavelengths. This is due to the electrons in the neon gas being excited and emitting photons of light as they return to their ground state.
Neon from a neon sign is an element. It has the symbol Ne and is in group 18 which is noble gasses.

All signs which actually contain the element neon are about the same color. However, some signs which contain elements other than neon are sometimes referred to as 'neon' signs. In this case, the signs with different elements are different colors than true neon signs.
No, neon gas in a neon sign is not a compound. Neon gas is an element, a noble gas with the chemical symbol Ne and atomic number 10. It is used in neon signs because it emits a bright red-orange light when electricity passes through it.
The next time you go to a grocery store or something look at the big sign. That sign might just have neon in it to make its color.

To build a neon sign factory.
Neon is obtained from air by fractional distillation.
No, the neon color in neon highlighters does not come from the element neon. It is typically a bright, fluorescent color that is used for coloring the ink in the highlighter.
The installation of a neon 'open' sign for a store can be as simple as mounting it to a window and plugging it in. But be careful! The neon sign is made from glass and is very fragile!
Neon
Neon is an element, classified as a noble gas, and it has nothing to do with burning wood. Neon does not burn, nor is it produced by burning.
Some of the oldest Budweiser neon signs were produced in the early 20th century when Budweiser started to produce beer cans and creative marketing strategies to target specific populations.
Neon is typically seen as a bright reddish-orange color when it is in its gaseous state and used in neon signs.
