My Phanotron tube appears to produce white light only. I can see purple light only between the electrodes. Is my tube working correctly ?

Yes, that is fine. Sometimes, depending on frequencies, you will not see any light at all unless the room you are in is totally dark. With lights out you can see it but with lights on, you cannot.
