I once saw a morph labeled as a 'purple' corn (no, they weren't lavenders). I asked the seller if they had any charcoal genes in them, because they almost resembled pewters. His response? Nope... they came from blizzards.
(Note: blizzards are double homozygous for charcoal and amelanism, for those of you who are unaware.)
I hate people who don't know anything about what they're selling. :P
