Please keep in mind that this rule only applies in North America. In Central and South America there are corals that have red touching black and some that are only red and black. Just FYI for travelers or people who dont live in the U.S.

And actually there's one or two species in the U.S. that are harmless colubrids but do have red touching yellow. I think its the longnose snake, if I remember correctly.
