incidentally @kel's green is not just any green, but specifically the brilliant grass-green 535 nm thallium emission line. Kel is a thallium dragon...the little weirdo.

@KitRedgrave @kel and, rather appropriately, Kel (like thallium) generally has to accompany other elements :p (thallium-only minerals are very rare; instead thallium tends to insinuate itself into the crystal lattices of other elements' ores)
@kara_dreamer @KitRedgrave *giggles* that's me, sneaking in everywhere and popping up where you least expect it!
