One is clear glass tubing with neon which produces a red One is clear glass tubing with neon which produces a red color, the second way is colors produced by the “ inert color, the second way is colors produced by the “ inert gasses” in the tubing’s with some florescent gasses” in the tubing’s with some florescent baked/painted on the inside. The third and final way is to baked/painted on the inside. The third and final way is to use colored glass in combination with neon or argon to use colored glass in combination with neon or argon to produce multiple colors produce multiple colors
