What colors can neon signs be?

Answered by Joseph Vos

Neon signs, oh how they captivate us with their vibrant and mesmerizing glow. These luminous beacons of light have the power to attract attention and add a touch of brilliance to any setting. But have you ever wondered about the range of colors that neon signs can display? Well, my curious friend, let me take you on a journey through the vivid spectrum of neon signage.

When we think of neon lights, the color that often comes to mind is that iconic orangey hue. This color is actually produced by the noble gas neon itself. Neon gas, when excited by an electric current, emits a brilliant orange light that has become synonymous with the term “neon lights.” It's this characteristic glow that has lent its name to the entire genre of illuminated signage.

But, my dear reader, the world of neon signage is not limited to just one color. There is a kaleidoscope of hues that can be achieved by using different gases and chemicals within the glass tubes of these radiant creations. Let's take a closer look at some of the other colors that can be achieved with neon signs.

1. Hydrogen – Purple-Red: By filling the glass tubes with hydrogen gas, a striking purple-red color can be achieved. This hue is often associated with a sense of mystery and allure, making it a popular choice for establishments aiming to create an enigmatic ambiance.

2. Helium – Yellow or Pink: Another gas that can be used to create stunning neon signs is helium. When excited by an electric current, helium emits a luminous yellow or pink glow. This color range adds a touch of warmth and playfulness to any sign, making it an excellent choice for venues that want to exude a cheerful and inviting atmosphere.

3. Carbon Dioxide – White: Believe it or not, white can be achieved in neon signage too. Carbon dioxide gas is used to produce this color, creating a clean and crisp glow that is often associated with modernity and sophistication. White neon signs can be seen illuminating the facades of trendy restaurants, sleek cocktail bars, and high-end boutiques.

4. Mercury – Blue: Ah, the cool and calming color of blue. Mercury is the gas responsible for creating this serene hue in neon signs. When a current passes through a tube filled with mercury vapor, a striking blue light is emitted. This color is often chosen by businesses that want to evoke a sense of tranquility or convey a cutting-edge and futuristic image.

These are just a few examples of the colors that can be achieved through the magic of neon signage. Each hue carries its own unique symbolism and can be used to enhance the atmosphere and messaging of a particular establishment. From the vibrant orange of neon to the captivating purple-red of hydrogen, the possibilities for creating eye-catching signage are endless.

In my years as a sommelier and brewer, I have had the pleasure of witnessing the power of neon signs firsthand. Whether it's the warm yellow glow of a brewery sign beckoning enthusiasts or the alluring blue radiance of a cocktail bar drawing in patrons, these signs hold a special place in the world of hospitality.

So next time you find yourself walking down a bustling street, take a moment to appreciate the colorful array of neon signs that illuminate the cityscape. Each one tells a story, captures a mood, and invites you to step into a world of possibilities. The world of neon signage is a vibrant and captivating one, and I hope this journey has shed some light on the myriad of colors that can be achieved through these luminous works of art.
