The exact saying words vary a bit, but the idea is: red touching yellow can kill a fellow, red touching black is a friend to Jack...
The trouble is that if you follow that rule, you're likely to be killing a harmless shovelnose or Western (or Texas) longnose snake, since coral snakes are adept at hiding,
and even IF you find one, they are so small as to have a hard time getting a hold of you for envenomation to occur. Coral snakes are in the elapid family & have serious
venom, but their fixed front fangs are weak & small, & non-retractable. You'd mostly need to try hard (pick up, or step on with bare feet) to get bit. Unlike a rattlesnake,
their fangs cannot swing forward to envenomate a flat surface (like your leg) even with their mouth open wide- they must get their mouth around their prey to be effective.
According to livescience.com, it's hard enough for them to get their teeth into human skin, much less leather boots. Some of them would rather hide their head & produce
microfarts to scare off predators...boy, that takes a real macho person to kill one, doesn't it? How pathetic...

Could everyone just learn to walk away & stop killing our wildlife please??? If you're that freaking afraid, you belong living in a freaking city.
