Most luminous signs use neon gas to produce bright and colorful lighting effects. Neon gas is commonly used because it glows brightly when an electric current passes through it, making it ideal for creating eye-catching signs and displays.
the way I've done it is by using argon-mercury with a non-phosphore coated yellow (novial) glass tube. Krypton, and Xenon, give off a dim white glow under normal gas fill pressures. Argon without mercury is dim lavender. Helium is a fleshy colored beige, and NEON of course, is a bright orange red... more red. I also have some old Uranium Glass that was rumored to actually have some real uranium in it... it seems to glow bright lime green without any power to it. But when lit up with Ar/Hg, it really glows a brilliant yellow-green!
No, not all neon signs actually contain neon gas. While neon signs were originally made with neon gas which produced a distinct red-orange color, other gases such as argon, helium, and mercury vapor are also commonly used in modern neon signs to produce different colors.
Neon gas itself is not poisonous. It is a non-toxic, inert gas that is colorless and odorless. Neon is commonly used in neon signs and lighting.
Neon is used in science to create neon lights which are used in a variety of applications such as in scientific equipment, vacuum tubes, and advertising signs. Neon is also used in cryogenics to provide extremely low temperatures for scientific research and in ion lasers for spectroscopy and holography.
The gas commonly used to make yellow-green neon signs is neon gas. When an electrical current passes through neon gas inside a sealed glass tube, it emits a bright yellow-green light.
The question is actusally related to the mystery of "What color is an orange ?"

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.

Krypton is the usual thought as it seems to relate to kryptonite which all Superman fans know glows green. The noble gases fluoresce in different colours in gas discharge tubes. Helium is white to orange, neon is red-orange, argon violet to pale lavender-blue, krypton white to greenish, xenon whitish to blue green at high currents and radon is not specified. So the Superman fans are right!

The most common neon color is fluorescent green. Neon green is often used in signs, clothing, and accessories to grab attention and stand out.

No, helium is not used in neon signs. Neon signs are filled with neon gas, which produces the iconic red glow when an electric current is passed through it. Helium is a colorless and odorless gas often used for filling balloons and as a coolant in some applications.
Its mostly Argon and a small amount of mercury. Its the main ingredients inside a flourescent lightbulb, which are used to light up billboards and highway signs. See the related link for more information on flourescent bulbs.
The gas used is neon.
