Nitrogen glows green - it's responsible for the green-ness of the Northern Lights. None of the other gaseous elements has a strong enough green line in its emission spectrum. Barium and cadmium do, but they're not gases.
The only green "nixie" I've ever seen appears occasionally in the bottom left of the screen in the Guitar Hero video game - irritatingly, I can't find a pic of the green one. It also appears in other <http://wiimedia.ign.com/wii/image/article/830/830801/guitar-hero-iii-legends-of-rock-20071026062738901.jpg> colors<http://img.gamespot.com/gamespot/images/2007/319/reviews/943274_20071116_screen001.jpg>, including traditional orange,<http://www.tfw2005.com/transformers-images/wallpapers/images/7008-4/Guitar+Hero+Soundwave+1600+x+1200.jpg>and not lit up<http://wiimedia.ign.com/wii/image/article/831/831151/guitar-hero-iii-legends-of-rock-20071029034132944.jpg>. I'm impressed by the realism - you can see reflections off the glass, the anode grid and the outlines of the unlit cathodes. Kudos to the game artists for putting a nixie in front of an audience that in all probability have never seen one in real life. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
