It is indeed as Gunny133 pointed out an extremely low dropchance from mobs in their respective biomes, I got the rainbow gun yesterday and it is super amazing, The rainbow can also be used to ward of incoming projectiles (the ones that can actually be destroyed) creating an arced rainbowshield above you.

Be warned though, finding the chest in the dungeon on hardmode if you're not very good geared will most likely result in agony and death on your part.
