This is getting interesting...never have seen a pure green ionized gas. There is a possibility it may have been a hybrid gas mixture. Since Helium produces a pale yellow and mercury will produce a blue color...possibly it was a mixture of a few types of gases. Also some ionized gas will produce different colors at different energy (voltage ) levels. Pressure also enters the equation. As far as any commercial vacuum tube regulators I have yet to see a pure green color.
