Neon signs

We've all seen neon signs before in cities late at night, mostly in Las Vegas. When you think of neon signs the first thing that pops into our head is that they are filled with neon gas; that is not the case however as neon can only produce a red color. The colors in order of discovery were blue (Mercury), white (Co2), gold (Helium), red (Neon). Then there were more colors made possible thanks to argon, mercury, and phosphor.

-There will be a spot on neon tubes in the class project I am in, expect to see this information in the video coming up, possibly even more details, much more details.
