Neon Light Colors: What Are The Brightest, Are They Illegal And Gasses Used

Discover the fascinating and vibrant world of neon light colors, from the brightest hues to the considerations that come with them. Explore the gasses used to create these eye-catching signs, popular alternatives, and the regulations you need to know about for using them in different settings.

Neon Light Colors: What Are The Brightest, Are They Illegal And Gasses Used

Key Takeaways

  • The natural color of neon gas when it glows is the iconic orange-red seen in many traditional neon signs.
  • Other gasses like argon and krypton can produce different shades of light, and phosphor coatings inside the glass allow for further variation.
  • Different neon light colors are better suited to different purposes and environments, and you can achieve a wider spectrum of bright hues with LED neon signs.
  • We supply high-quality custom LED neon signs for business or personal use, with flexible personalization options and cutting-edge technology.

What Are The General Neon Light Colors?

The color of a neon light can vary, but the most common ones include red, blue, green, and yellow. The very first neon light, created by Georges Claude in 1910, emitted a vibrant red-orange glow. This is the natural color you get when you electrically charge pure neon gas.

Other colors are achieved by using different gasses or adding phosphor coating to the inside of the glass tubes. Argon gas can be used to emit a blue light, while a mix of neon and argon produces a green or yellow hue.


These vibrant displays have made neon lights an iconic signage solution for commercial and decorative applications.

What Color Does Pure Neon Glow?

Pure neon gas glows with a bright red-orange color when electrified. This occurs due to the excitation of neon atoms by an electrical current, causing them to emit light at specific wavelengths.

The red-orange glow is the iconic neon signage, and other colors can be produced by using other gasses or adding a phosphor coating inside the glass. In comparing LED neon vs glass neon lights, you will find that many more colors can be achieved with the LED technology.

What Colour Is Neon Naturally?

Though normally invisible, the natural color of neon gas when electrified is a bright red-orange when electrified. This hue comes from the neon’s atomic structure, which emits photons of light at certain wavelengths when excited by an electrical current.


Other gasses may need coatings or additives to produce different colors, but neon naturally gives off this red-orange glow. This was first showcased by Georges Claude and remains a hallmark of traditional neon signs. It is the classic, iconic neon light color.

How Is Color Produced In Neon Signs?

Color is produced in neon signs via the excitation of atoms in the gas-filled glass tubes using an electrical current. The red-orange glow is emitted from pure neon gas, but different colors can be achieved by combining with other gasses or adding colored coatings to the glass.

Argon produces a blue light, and mixing it with mercury results in a bright white or green hue. Phosphor coatings inside the glass tubes can also alter the color of the emitted light. With a range of gasses and coatings available, a broad spectrum of vibrant hues can be achieved.

How Do Neon Signs Produce Different Colors? Role Of Its Electrical Discharge

The color of a neon light can be altered through a combination of gas mixture and tube coating. By mixing different gasses like argon and mercury inside the glass tubes, and by adding phosphor coatings, the visible color of the light will look different. The appearance of the light will also be affected by how dirty the tubing is, so it’s important to know how to clean neon signs.

Explore variations in gas mixture and tube coating to get the exact color hue you want for your neon sign. Skilled craftsmen are very knowledgeable in what colors can be achieved.

What Is The Process Of Neon Gas Excitation?

When electricity passes through the neon gas in a glass tube, it excites the atoms. This causes each atom to release energy in the form of light. These bright emissions are vibrant and colorful, producing the distinctive glow of neon signs. It is the process of exciting gas atoms with electricity that makes neon signs shine.

What Varieties And Colors Can Neon Lights Be?

Neon lights offer a range of colors beyond the classic orange-red hue. A full spectrum of shades is achievable by combining gasses and phosphor coatings:

  • Argon emits a blue light.
  • You can add mercury to argon to create white or green.
  • Phosphor coatings can allow for shades like green, purple, and yellow.

This versatility takes skill and expertise, and it is what makes neon lights so popular for different applications. You will find the technology in eye-catching signage and decorative lighting in various settings.

Can Neon Lights Be Any Color?

The color of a neon light can vary significantly through the use of different gasses and coatings. As we have mentioned, you can combine gasses in different ratios to achieve varying shades of blue, white, or green, and add phosphor coatings for shades of green, purple, and yellow.

However, this makeshift approach to customizing the color of neon signs brings limitations. Shades like true purple or pink can be challenging with the methods available in creating neon signs. LED neon signs, however, offer a wider spectrum of bright colors to create exactly the aesthetic you want.

What Are The Brightest Neon Colors?

The brightest colors in neon signs include vibrant red, blue, and green. With the brightness of these hues, they make eye-catching signage, advertising displays, and decorative lighting. With their bold, intense appearance, they attract attention and add a dynamic element to various settings.

If you want a broader range of vibrant colors to choose from, our custom LED signs are available with flexible design options and cutting-edge technology. Use our service to create high-quality pieces that are durable, energy-efficient, and offer the same iconic look with a wider range of bright color choices.

What Gasses Are Used In Neon Signs And Their Colors?

Neon signs actually use various noble gasses to produce different colors and effects:

  • Neon emits a red-orange glow.
  • Argon creates a stunning blue light.
  • Mixed with mercury, argon can produce green or white hues.
  • Krypton emits a pale white or light purple light.
  • Xenon produces a blue glow.

By exciting these gasses with electrical currents, they release photons at specific wavelengths that result in their distinct colors. Neon and argon are the most commonly-used gasses, but krypton and xenon are sometimes used in specialized applications.

How Do Adding Different Gases Create Neon Light Colors?

You can create a diverse range of colors by combining different gasses in neon lights. The most common blend is to mix argon with mercury to produce a white or green glow. By varying the ratios of gasses in relation to one another, you can further expand the color palette.

For example if you combine argon and neon in different ratios, you can shift the color from blue to purple. Similarly, a blend of krypton and xenon in different ratios can create a range of hues from pale blue to light purple. These creative gas combinations give you a degree of flexibility when creating custom neon light colors, though not as much as you get with LED neon signs.

Why Is Neon Unique Among Noble Gases For Signage?

Neon stands out among the noble gasses for neon signs due to its distinctive red-orange glow. This hue is instantly recognizable, and it is the synonymous color with neon signage. Other noble gasses emit paler colors when electrified, but neon’s natural color is truly iconic and works well for various applications.


Generally speaking, neon is the preferred choice for many neon sign designers and enthusiasts.
