See the spectrum here, it is multicoloured: http://astro.u-strasbg.fr/~koppen/discharge/nitrogen.html Here's one of air: http://www.scitechantiques.com/MMs_project/reference%20paper/Air_Spectrm_5mm_labeled.jpg It seems to depend on the amount of water in the air what colour you get, the hydrogen makes it more red.
