Color wise, it will depend on what the red Pembroke is carrying, IF it is carrying for tri, then you might end up w/a black & white (tri) "Cardibroke/ Pemigan."
The point color of the black & white Cardi potentially could be a factor in the color as well.
Kate, well depends on her background. Cardigans have several dilutes in their genetic soup which could cause her color to be that light. Pembrokes have a couple, one of which could/would cause the same coloring.
