A gas discharge tube that is capable of lighting in different colors. The gas discharge tube, which may contain neon and mercury vapor, and which has its inner surface coated with a photoluminescent layer, is energized with a pulse current. The resultant color of the light emitted from the gas discharge tube depends on the combination of the pulse shapes and duty factors constituting the pulse current.
