Electricity flowing though tubes filled with the different gases ionize the gas which starts glowing in different colors depending on the gas composition. The name NEON Sign originated in early 1910th when signs were red and gas used to fill tube was neon.

Sorry, but it is electricity. The glass tubes are filled with a neon gas. The colors depend on which gas is in there. There are different ones. They are the noble gases on the periodical table. One makes green, one makes red, one makes white, one makes yellow and so on. Then, once the gas is in there, then they run electricity through the tube and it glows. The noble gases glow when electricity is run through them.
