Can you change the color of a neon sign? (2024)

Neon signs have long been a popular choice for businesses and individuals looking to attract attention from customers. The bright and captivating colors of neon signs can instantly attract attention and create a memorable visual impact. But what if you want to change the color of your neon sign? Can it be done? Don't skip this article if you want to find your answer.

The basic principle of the color of neon signs

Based on the use of different gasses and phosphorescent coatings. Some common basic principles and colors in neon signs:

Neon gas

Neon gas produces a red or orange-red color, and this is the most common color used in traditional neon signs.

The red color of neon signs is created by ionized neon gas in a glass tube. When electric light is passed through neon gas, it creates a series of special molecules and ions. When electrons in neon gas move from a higher energy level to a lower energy level, energy is released as light. This creates the characteristic red or orange-red color of neon gas when used in neon signs.

This color is often used to create a striking look and attract attention. This is the most traditional and popular color in classic neon signs, such as cafe, restaurant or store signs. Orange-red creates a warm and inviting feeling when seen, and it is often used to evoke emotions and stimulate customers.


Gas Argon gas produces a blue color when ionized in a glass tube forming special molecules and ions.

When argon gas is excited by electricity, electrons in the gas move from a higher energy level to a lower energy level. This process releases energy in the form of blue light. The blue color of argon gas creates a beautiful lighting effect and is often used to create celebratory lighting, decorative lighting and unique lighting effects.

The blue color of argon gas creates a cool, calming feeling and is often used to create relaxing and calm spaces. It can also be combined with other colors to create diverse and interesting visual effects. Blue is also commonly used in lighting effects during musical performances, special events, and advertising signs to attract attention.

Krypton gas

When krypton gas is ionized in a glass tube, it produces a series of special molecules and ions. When electrons in krypton gas move from a higher energy level to a lower energy level, energy is released as green light.

The green color of krypton gas creates a bright and attention-grabbing lighting effect. It is often used to create unique celebratory banners and lights, especially during special events, advertising, and performances. Green brings a fresh, vibrant and youthful feeling when seen.

Phosphorescent coating

Phosphorescent coating is used to change the color of the light emitted by a neon sign. This overlay can alter or enhance the original color of the mark.

When creating neon signs, the combination of gases and phosphorescent coatings can produce a variety of colors. Professional technicians can combine gases and phosphorescent coatings at will to create unique and customized colors for neon signs.

Is it possible to change the color of neon signs?

Traditional neon signs are made using glass tubes filled with specific gases that emit different colors when an electric current passes through them. The color of the light emitted from a neon sign is determined by the type of gas used in the tube. For example, neon gas produces a red-orange color, while argon gas emits blue light. These colors are fixed and cannot be changed without changing the gas inside the tube.

However, advances in technology have allowed for the development of LED (light-emitting diode) neon signs, which offer more color customization. LED neon signs use flexible LED strips to replicate the look of traditional neon but with the ability to change color. These signs are often available with remote controls or smartphone apps that allow you to switch between different colors and even create dynamic color changing effects.

If you already have a traditional neon sign and want to change its color, there are several options available. One approach is to add colored gels or filters onto the glass tube to change the appearance of the light. This method can be used to create a temporary color change as the gel or filter can be easily removed or replaced. However, it is important to note that this technique can affect the brightness and clarity of the sign lighting.

Another option for changing the color of a traditional neon sign is to have it professionally reprocessed. The process involves removing the existing gas from the glass tube and replacing it with another gas that emits the desired color. However, reprocessing neon signs can be complex and expensive as it requires the expertise of a skilled technician and may involve sourcing specific gasses.
