Haha! Fartipoo! I love it!
I think the problem I have with people that name their axolotl colours with new and fancy names is that most people won't know what on Earth that actually means - because only the breeder will know. And that leads to confusion over what the animal is. I've seen Wildtype axolotls advertised as melanoids, Leucys advertised as albinos...and those are fairly easy mistakes to make if you're new to the hobby. Calling a black and gold axxie a 'bumblebee' axolotl, for example, is going to lead to problems, especially if a customer believes they have something unique and later find that the animal they have purchased has been given a false name to make it sound rarer. I won't lie and say that I don't find certain morphs gorgeous, because I do, but I care more that the axolotl has been bred by someone who really cares about their babies and not just about the dollars.
I think calling an axolotl 'purple' is okay, though, as it's not really a misnomer - they are purplish, and you haven't tried to label them as 'Amethyst Mist' axolotls or similar, which would make them sound like some sort of established breeding variety (or potentially a species of violet, one or the other). It's like on Ebay, where some sellers will claim, no matter what the item, that it is **RARE!*** - even when it is, in actuality, not all that hard to get hold of. I once saw someone call their WTs with gold spots "Gold Rush" axolotls. Toothless also has these spots. But he is a Wildtype, pure and simple, because no matter how pretty the spots, he is a WT first. I didn't want to call him something that would just confuse people and make them think he was something he wasn't.
I remember having fancy mice and the sheer number of colours, fur textures, etc was mad. We also have two dogs; one is a labrador (she has a daft KC name and everything >.<) and the other is a breed that's not even recognised as a breed, except by the Rare Breed Club. She's a Patterdale Terrier and there are loads on our street alone. So she's definetely not rare. More to the point, most 'purebreeds' were mongrels once upon a time, so the whole idea of 'purebred' animals is fundamentally flawed - the labrador, for example, was created from a mixture of breeds, including one now-extinct breed (the Water Spaniel). Trying to make everything 'elite' when it's a simple matter of breeding, which, let's face it, is not the be-all and end-all, whether mongrel or purebred, just seems daft to me. As long as the animal is loved, and healthy, that's great.
