Each element give off a particular color when heated in a flame. (Some are colorless). Copper gives off a green flame but to do that there must be some copper compound IN the flame. (there are many other elements that also could be causing a green flame).
And copper is absolutely not the cause of blue gas flames on a kitchen stove or the blue inner core of a candle flame. From now on, any mention of blue or green flames will refer only to flames not involving copper or barium, or any other element that gives off blue or green wavelengths.
