Neon actually exists in the air we breathe, but only in trace amounts. As previously mentioned, pure neon gives off a deep red glow at normal levels. Pure-neon light represents an extremely efficient light source for signs. Mercury vapor creates a soothing and gentle, blue glow.
If you watch street lights when they first come on, you may catch a glimpse of the blue color from mercury vapor as most of these lights rely on mercury for their chemical makeup. Most neon signs have either neon or mercury vapor in them, depending on whether the manufacturer wants to create colors with a cool or warm base color. When a manufacturer wants cool colors, like green or purple, he or she likely uses mercury rather than neon. Craftsman typically mix argon with mercury to produce a stronger, more vibrant blue color.
Sometimes the manufacturer paints the inside of the glass tubing with ultraviolet-sensitive phosphors to create different colors. The mercury in the combination gives off ultraviolet light and makes the phosphors glow. When you see a neon sign with clear, effervescent blue, green, yellow, or white coloration, the tube likely contains argon gas. In colder areas, manufacturers can add helium to the mercury and argon mixture to make the light heat faster.
Alone, helium creates a pinkish-red glow. Of the gases on this list, pure helium is one of the most difficult to procure. Most industrial-grade helium results from radioactive decay or comes from a natural gas deposit. Xenon produces a deep lavender glow. Craftsmen use xenon primarily in strobe lights and photography, though they also add it to the mixture inside a neon light. When combined with other noble gases, xenon shines in a wide array of colors. Krypton emits a low, whitish-yellow glow.
Because of this characteristic, manufacturers use krypton to produce a large variety of colors. When craftsmen add krypton to lighting tubes, they typically rely on colored glass to produce the perceived color. Outside of neon signs, manufacturers also use krypton gas for safety lighting, including airport runway lighting. Every neon light represents a complicated chemical reaction to produce beautifully vibrant colors.
When you look at your neon signs and the signs of businesses around you, see if you can guess what gases create those glowing lights. How to Build Brand Awareness with Custom Signs Ever wonder why it is easy to recall what a company name is and the product it sells based on having seen an image or logo?
This is because successful companies recognize the inherent value in generating brand awareness, which is the extent to which the brand is recognized by potential customers and correctly associated with a particular product or service. A custom sign is one of the most seamless ways to bring your company name to life and improve brand awareness. Incorporating a logo into your custom sign will help draw in potential clientele, help produce brand recall, and improve market perception.
The icon of your business sets the tone for consumer outlook and company persona, so it is important to take the following into consideration when determining what image you want displayed. Who Is Your Target Audience? Because your name and consequently your sign is oftentimes the first visual a potential customer sees, it is important to cater understand who your target audience really is.
What kind of demographics and psychographics create your typical customers. These answers should help define what logo and sign should be created. For example, if your company is one that offers a luxurious and aristocratic product, your custom sign should not be haphazard and immaturely created.

Updated October 06, Key Takeaways: Neon Lights A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them.
But it is pretty easy to build a gas discharge tubesuch as a neon lightwhich reveals that inertness is a relative matter. One need apply only a modest electric voltage to electrodes at the ends of a glass tube containing the inert gas and the light begins to glow.
It's much easier to explain why neon isn't inert in a discharge tube than it is to explain why it is inert to chemical reactions. The voltage across a discharge tube will accelerate a free electron up to some maximum kinetic energy. The voltage must be large enough so that this energy is more than that required to "ionize" the atom.
An ionized atom has had an electron plucked out of an orbital to make it a "free" particle, and the atom it leaves behind has become a positively charged ion. The resulting plasma of charged ions and electrons carries the electric current between the tube's electrodes.
The photo above shows a gas discharge sign designed by Sam Sampere of Syracuse University. This sign incorporates a neon discharge tube the orange word "Physics" and mercury discharge tubes the blue word "Experience" and the outer frame.
The sculpture at the bottom of the sign represents the electric and magnetic fields of light. The white and yellow sine waves in the sculpture are actually fluorescent lights. These fluorescent lights are mercury discharge tubes with special coatings on their inner walls. The ultraviolet light emitted by the mercury discharge inside a tube is absorbed by the coating, which subsequently emits light of a different color and with a lower photon energy.
Depending on the exact material of the coating, a whole range of colors can be obtained.
