Golden Apple Snail
Ivory Apple Snail
Black Apple Snail
Blue Apple Snail
They should be called Mystery Snails, as they are just one of over 100 species of Apple Snails.
As for the different colors, stores usually only deal with five - Gold, Ivory, Black, Albino and Blue, as these are the ones bred at fish farms. There are a lot more that exist, including Jade, Yellow Stripe, Light Striped Purple , Dark Striped Purple, Magenta, etc, but these are usually only available from private breeders.
I've had purple and magenta snails, you just have to get them from a breeder instead of buying from a big box store. I ordered mine from a member on aquariacentral.com and they were absolutely beautiful:) She does a great job of shipping them to you as well.
In this thread you can see pics of some really pretty purple ones.
