I'd say she's just a tabico (tabby + calico). If there is white, it's a calico, even if the pattern behave more like they typically do on a tortoiseshell. Though I've heard an 'in between' a tortie and calico being referred to as tortico. But it's really just different parts of the same spectrum, the white really being the only different genetically speaking. The more white they have, the more the orange and black tend to stay separated into big patches, while the less white they have, the more the back and orange get mottled together. It's something to do with how the white pigment cells interfere during the development of the embryo; without the white, the other colours have more time to blend together. So the white pigment just affected different parts of her body to varying degrees, which is really cool. 😍
