That wool can make it tricky to identify colors at first - the pigment and banding pattern is s-t-r-e-t-c-h-e-d out along the length of the hairshaft, so it doesn't look the same as on normal fur. Still, if you blow into the shorter fur along her back you should be able to pick up the ring pattern.
