1915: The Neon Tube sign is patented by Georges Claude, and later exploited by Las Vegas.
-So, you might already know that neon is one of the “noble” gases of the periodic table, which glows an orangey-red color when electrons run through it. But what about all the other colors on a typical “neon” sign? Well, sorry to say, those aren’t neon. To get shades of blue, typically argon is used with a dash of mercury. Helium can be used for a nice pink glow; xenon radiates a cool purple, while krypton yields- what? Green, you say? Nope, sorry Superman, it has more of an off-white tinge. From there, certain gases can mingle to produce colors like green and yellow, or sometimes the tubes are coated with fluorescent powders to tweak the shading. But neon typically doesn’t play nicely with others, so it’s only used to produce that one color.
(Check out Vegas Vic’s scarf. There’s your neon.)

There is another noble gas that wasn’t invited to the party: Radon. That stuff is radioactive, yo.
