Neon is a bright, reddish-orange chemical element with the symbol Ne and atomic number 10. It’s found on the right side of the periodic table along with the other noble gases (helium, argon, krypton, and xenon). British chemists Sir William Ramsay and Morris Travers discovered neon in 1898 while studying liquid air. When they ran a high voltage through a sample of the gas, it glowed a vivid crimson. Ramsay’s son suggested the name “neon” based on the Greek word for new, because its glow was unlike any other known color.
It’s unreactive, so it’s used to protect equipment from oxidation or other chemical reactions. It’s also used as a refrigerant, and in neon signs to create that classic glowing effect.
When used appropriately, neon can add a pop of color that’s both eye-catching and stylish. It pairs well with dark colors, such as grays and camel shades, or neutrals like natural linens and light wood tones. It’s best to stick to a single neon hue in designs, though, as too many can make the overall design look busy and crowded.
Aside from neon, other noble gases produce a variety of colors when electricity runs through them. Helium produces a bright orange or pink shade, krypton emits a pale white or blue, and xenon gives off a cool blue tint. Radon can also generate a hot red discharge, but it’s not commonly used for signs due to its radioactivity.
