I haven't been on the web since Friday, or I'd have replied earlier.
I don't know of any better way to tell the difference between anerythristic and charcoal corns. From what I've read on the kingsnake.com corn snake forum, that is not 100% reliable in adults. and hatchlings need a few months to develop their red/yellow colors. Which makes identification of the babies more difficult than the adults.
