Neon lights get their name from neon gas. Neon is an element, or substance made of just one type of atom. But Ablon can also make glowing art with the gases of other elements, such as helium and argon.
Different gases produce different colors of light (see Neon Rainbow). Neon glows a fiery red-orange. Argon mixed with the element mercury shines bright blue. But there are only so many colors Ablon can make with gas alone.
To create even more hues, Ablon uses tinted glass and powdered fluorescent (flor-ESS-ent) coatings. When a fluorescent material absorbs light, it glows with its own color.
Ablon regularly uses about 40 colors of light. But he could easily create more with different combinations of gases and coatings. “There are countless possibilities,” he says.
