Neon, will be usefull for neon lightbulbs and will act like tungsten, but in the gas form. The color of the gas can be changed by setting its deco color. Its not flammable and when it heats up it becomes light white (or the color its set to) like tungsten when it heats up. When it cools down, the color its set to becomes dark, but i think you will decide yourself whats the temperature limit because i have no idea of its temperature limit. Thank you for reading and i hope this will be added.

Yeah? And also, the default of the color is white i guess
