I have a Rosy boa that is gray with orange highlights, what is the species or is it a mutation?

I also have a San Mateo rosy boa, off white with an orange stripe down its back, is it is a different species than the above one? Or a color mutation of the rosy boa or a sub species?

How many different species of rosy boa are there?

How many mutations of each?

Websites that show pics of each? Kim
