The vivid colors seen in advertising lights are the result of different neon gases that each tube contains. Different gases burn at various temperatures resulting in these colors. For example magnesium produces the bright white color light.

∙ 15y agoElectrons in the outer most shell of neon atoms can be excited with various forms of energy. In neon lamps, these electrons are excited by the collision with another energetic electron (from the electric current source). The kinetic energy of the energetic electron can be transferred to the outer shell electrons, causing the outer shell electron to rise (excite) to a higher 'energy level'. However, this higher energy level is only maintained transiently and the excited electron falls to its original energy level, and the extra energy is released as electromagnetic radiation. If the elctromagnetic radiation is in the visual range (380 nm to 750 nm in wavelength), then it can be observed as light.

Neon is mixed with other gases to cause an inert reaction. Oxygen for Red, Argon for yellow etc. At the ends of the tubes are electrical devices called exciters which cause the color to show through the tube when they are plugged in.

∙ 11y agoCertain gases emit different colors in "neon" signs (which can contain elements beside neon) because of their different electron configurations. When an electric current is passed through the gas, some of the electrons in the gas molecules are excited. These electrons then return to their ground state by emitting a photon, a particle of light. The energy of the photon (which in turn determines the color of the photon) depends on the difference in energy between the excited state and the ground state. Since this energy gap is different for different elements, various gases can emit various colors of light.

∙ 9y agoThe color of neon light will depend on the gas in the tube. The color is naturally red, but when other gases and chemicals are mixed, they produce different colors.

∙ 12y agobecause people think that neon comes from the ancient Greeks and that many colors were created by them as they were experimenting with food and that is how neon colors came to be
Wiki User
∙ 14y agoBecause the lights are filled with gases and each gas gives a different color. There are no two gases that give off exactly the same color

∙ 14y agoThere is different mixtures of gases with each kind of color. Gases such as argon, neon, helium, mostly noble gases.

Do neon lights have gas?
Neon is one of the noble gases - helium, neon, argon, krypton, xenon. Gas discharge lights, commonly called neon lights, will produce different colors depending on which gas is used. Neon itself produces an orange light. The Wikipedia entry ' Noble Gas' has a nice illustration near the end showing the colors produced by each of the above gases
How many different colors can now be produced in neon tubing?
3
What gases make up neon colors?
Look to the far right of the periodic table. Those are inert gases. Neon among them. On my chart in the "Life Science Libary" "Matter" book they were in tubes and electrified. They all had unique colors. By mixing them you have a pallet of electric light.
What are facts about neon lights?
I don't know THAT'S WHY I'M LOOKING IT UP.
What is man made plasma?
Man Made plasma can be found in Fluorescent and Neon Lights.
Is there a neon white?
Yes, but the gas is carbon dioxide, not neon. Actual neon lights glow red. Different gases glow different colors.
Are neon lights made up of neon gases?
There is only one neon gas. It's name is neon. It is an element, and is on the periodic table of elements. It produces a red glow. There are other gases used in neon lights. Here they are along with their color of glow: Helium, peach glow. Argon, sky blue. Krypton, pale mauve. Xenon, pale violet. These colors combined with different colored glass make the neon signs you see every day be in all colors.
What colors of under-glow neon lights would go good with a olive green color vehicle?
green or white
Does neon glow in the dark?
Neon does not glow in the dark but it does glow in black light or UV light. Because neon colors are so bright when illuminated with light, it gives the appearance that neon colors would glow in the dark.No, it is a colourless gas but it will glow red if you pass an electrical current through it.Neon is also another way of describing brightly coloured things, but they don't glow in the dark either.
What does neon gas contain?
Neon is a gas. It does not contain anything as it is an element.
What are some practical uses for neon?
Uses for neon gas include lighting up neon glow lamps and electric tubes. Neon is classified as a noble gas.
Are all neon lights made up of neon gases why?
No. Only the lights that give off a reddish light contain actual neon. Different color lights contain different gasses such as helium or argon. This is because every substance has a unique emission spectrum which dictates what colors of light it will give off if its electrons are excited such as by an electrical current.
What is in glow sticks that make them glow?
There is a chemical in the glow stick produces energy when shaken or snapped. Much like neon lights, the energy intensifies rapidly but will fade after time.
Do neon lights have gas?

Can LED lights be neon lights at the same time, or are neon lights different?
Neon lamps and neon signs are NOT incandescent. The gas is not glowing because it is hot, but because it is ionized, and the current is passing through it. this is the web where I read about neon lights. createneon
What noble gases are used in neon signs?
some are: neon-for a strong red glow argon- for a light blue color helium- for a pinkish red glow xenon- for a bright lavender glow krypton- for a yellow- white radon- for a yellowish greenish. and many more.
Is neon used in glow sticks?
Scientists have extracted the element neon from space and made into a "liquid neon" which they sell to neon glow stick factories, which is then put into the neon glow sticks.
