A real neon sign only glows one color
HERE’S THE INTERESTING PART
We have been living a massive linguistic lie this entire time. A true "neon" sign only naturally glows a very specific, aggressive reddish-orange when electrified. If you see a vibrant blue, green, or yellow sign hanging in a dive bar, it is actually filled with entirely different noble gases like argon or krypton, mixed with a little bit of mercury and a lot of deception.
One discovery leads to another.
