How Do Manufacturers Produce Neon Signs of Different Colors?
April 21, 2025
Ever walked past a neon sign and thought, “How do they make that glowing green or electric purple?” You’re not alone. These signs are more than just flashy lights—they’re mini science experiments wrapped in art. Let’s dive into the colorful world of neon signage and how experts like LED Lights and Signs, a trusted sign manufacturer in Houston, bring them to life.
The Colorful History of Neon Signs
Neon signs first lit up the streets of Paris in the early 1900s. From there, they took over cities around the globe, transforming plain storefronts into glowing beacons of personality and flair. Over a century later, they’re still glowing strong—though the tech and techniques have evolved.
What Exactly Is a Neon Sign?
A Peek Into the Science
Neon signs aren’t just pretty—they’re physics at work. These signs are made from long, narrow glass tubes filled with gases. When you add high-voltage electricity? Boom—glow time.
Why Neon Signs Still Wow Us Today
More Than Just Light
They’re vibrant, nostalgic, and irresistibly eye-catching. Whether it’s a cozy café or a trendy boutique, neon signs create instant ambiance. And guess what? It’s not just neon doing the work—other gases and coatings play a huge role, too.
What Makes a Neon Sign Glow in Color?
The Role of Gas Inside the Tubes
Different gases give off different colors when electricity passes through them. For example:
- Neon gas emits red-orange.
- Argon gives off blue.
- Helium produces a pale yellow.
- Krypton and xenon bring in subtle purples and whites.
Colored Glass Tubes vs. Clear Glass with Coating
Manufacturers use either tinted glass tubes or clear ones coated with phosphor powders inside. These coatings fluoresce when the gas lights up, creating a wide range of colors.
Common Gases Used in Neon Signs
Pure Neon Gas
The classic neon-red color? That’s 100% neon gas doing its thing inside a clear tube.
Argon + Mercury = A Cool Blue
Add a drop of mercury to argon gas, and you get a sharp blue glow. Use that same combo inside a coated tube, and the color possibilities go through the roof.
How Are Different Colors Achieved?
Phosphor Coatings for a Rainbow of Options
Manufacturers use different phosphor coatings inside the tubes. When excited by UV light from the gas, they glow in various colors. Think of them like neon’s secret wardrobe.
Tinted Tubes Add More Pop
Want a deeper shade or a softer hue? Use tinted or painted glass tubes. They help customize the exact vibe you’re going for—whether it’s electric lime green or a vintage pastel pink.
Mixing Gases and Coatings
Sometimes it takes both gas combos and coatings to hit the perfect color tone. This is where expert craftsmanship makes all the difference.
Step-by-Step: How Neon Signs Are Made
Making neon signs is a true art. Here’s how the pros at LED Lights and Signs do it:
Bending the Glass Tubes
First, glass tubes are carefully heated and bent into the desired shape or lettering. It takes a steady hand and a lot of skill.
Adding Electrodes
Metal electrodes are attached to each end of the tube. These connect to the power supply and help excite the gas inside.
Filling with Gas and Sealing
After evacuating air from the tube, the desired gas (or gas mixture) is pumped in. Then, the tube is sealed, tested, and lit up. Voilà—your custom sign is born.
What About LED Alternatives?
LED Signs vs. Neon Signs
Some folks prefer LED signs because they’re energy-efficient and super versatile. But here’s the deal: nothing beats the aesthetic of real neon. Neon has that warm, vintage glow that LEDs just can’t fully replicate.
