A Matilde parece-me uma bonita sable.
Aqui há mais algumas explicações sobre as cores para quem quiser entreter-se:

Este é o que eu já tinha colocado mas volto a colocar pois assim ficam aqui concentradas neste tópico as diferentes informações que recolhermos:

E aqui coloco outro resumo em inglês (para os “experts” traduzirem…)
The albino is white with red eyes and a pink nose. A dark-eyed white can have very light eyes and can possibly be confused with an albino. These can actually range from white to cream colored with the whiter the color the better. A dark-eyed white (often called a black-eyed white) is a ferret with white guard hairs but eyes darker than the red of an albino.
The sable has rich dark brown guard hairs with golden highlights, with a white to golden undercoat. A black sable has blue-black guard hairs with no golden or brownish cast, with a white to cream undercoat.
The chocolate is described as warm dark to milk chocolate brown with a white to golden or amber undercoat and highlights.
A cinnamon is a rich light reddish brown with a golden to white undercoat. This can also be used to describe a ferret with light, tan guard hairs with pinkish or reddish highlights. Straight tan is a champagne.
A silver starts out grey, or white with a few black hairs. The ferret may or may not have a mask. There is a tendency for the guard hair to lighten to white evenly over the body. As a ferret ages each progressive coat change has a higher percentage of white rather than dark guard hairs. Eventually the ferret could be all white.
White patches on the throat might be called throat stars, throat stripes, or bibs; white toes, mitts (sometimes called silver mitts), or stockings go progressively further up the legs.
A blaze or badger has a white stripe on the top of the head.
Panda has a fully white head.
A siamese has an even darker color on the legs and tail than usual and a V-shaped mask; and a self is nearly solid in color.
Com o meu é que não há confusões…
