1) I knew the doggerel (albeit in Italian language), even if it's useless in Italy, just because I'm a nerd and it happened to be in a book a read when I was a kid, so I knew the difference between a milk and a coral snake (in fact, in Italian they're referred to as Coral and False-Coral snake);2) You're giving me way too much credit, I'd love to say that was my intention, unfortunately I couldn't even if I wanted to, because I don't have the kind of details in a character description, so I must keep it generic enough to suit the character background. Of course, we must keep in mind that the character lives in a fantasy world, where our rules may or may not apply, so there's no need to be SO specific, especially when it comes to something arbitrary as color. I chose those colors just to stress the fact it is a venomous snake and to match her clothing, but it's nice to see someone looking at your work for more than a secondThank you.
