The Rainbow of Neon Signs: How They Achieve Various Colors and Shades

The obvious question you may have is where your custom neon sign comes from. While some lights may retain their original color after being turned off, others will appear clear. This is how these lights can shine so brilliantly and brightly when they are made of transparent glass.

If you believe all neon signs only contain neon, then you are seriously mistaken. To understand the inner workings of neon signs, read this article. The combination of gasses is necessary for neon signs to shine as brightly as they usually do. A custom neon sign is an artistic process that requires a lot of effort.

The majority of neon signs are made by filling a tube of glass with various gases. Mixing multiple gases with neon to make different colors is possible in custom. This is not the only factor that affects the color of your signage. It also depends on the gas used as well as the type and amount of inert substances used in the manufacturing process.

The following gases can be found inside a custom fluorescent sign.

It was clear to see. neon signs got their names from the staple gases used in the manufacturing of signage. Not listing it in the first position would have been considered an offense. Neon exists in our air. Even if we aren’t geeks, likely, you wouldn’t be aware of its existence. Yes, it is in the air, though only in trace amounts.

Therefore, manufacturers can easily obtain pure neon because they only need to fill a few tubes. Pure neon gives off a deep, red glow at normal levels. When you start filling the tube up with more gas, it will become paler or even pale, making the sign one of the most loved colors.

You will love this fact if your business is a small one. Pure neon signs have a high-efficiency light source that consumes less energy than their counterparts.

  1. Mercury Vapor

To create a cool base color, a manufacturer could use mercury vapor. Mercury Vapor has a subdued, bluish glow. The gentle glow of mercury vapor can be seen in the tube lights before they turn on completely.

The combination of neon and mercury vapor can be used to create signage depending on the client’s choice. Many manufacturers use mercury vapor to produce cool colors such as purple or green.

  1. Argon

Argon is your gas of choice for a more intense, vibrant blue color. Sometimes, the manufacturer can paint the inside of the glass tube with ultraviolet-sensitive phosphorus to create the illusion of different colors. The mercury inside the tube reacts with phosphorus and emits ultraviolet light, making the phosphorus shine brighter. Neon signage may have argon if it displays neon colors like effervescent green, yellow, and white.

  1. Helium

If your sign is in a colder location, the manufacturer who supplied it will likely inject helium into the tube of the sign’s tube. This will speed up its healing. Pure helium will give off a pinkish to a red glow. To make it soothing for the eyes, helium can be mixed with mercury or even argon. Of all the gasses on this list, helium has the hardest to obtain. Most industrial-grade, radioactively decayed helium is obtained from siphoning off natural gas deposits.

  1. Xenon

Xenon is responsible for the classic purple glow. It can reflect a range of colors if it is mixed with other noble gases. Although it’s most commonly used by manufacturers for photography and strobe lamps, xenon can also be found in signage that uses pure neon.

  1. Krypton

Krypton emits a low-key whitish/yellow glow. This makes it possible to create various colors with the gas. Krypton is commonly added to neon sign tubes by neon sign manufacturers. The color of the glass is what emits the perceived color. Krypton can also serve as safety lighting for airport runways and other signs.

Neon signs represent complex chemical reactions that produce vivid colors. Because of this, they cannot be called “neon.”

You can also talk to your provider about what gases are available to alter the color of neon signs.


Custom neon signs are growing in popularity. These signs can also be found in restaurants that are quirky or offices that promote a casual, relaxed atmosphere. Home decor is also being enriched with neon signs.
