I suppose it’s possible. No one breeds for that color so it would be hard to know how common it is or if it is the recessive color.
I do know that in Brittanys orange is recessive; but don’t know how that plays with the white pattern (which I have heard is a separate gene) which is always present to some degree. The other standard color is liver, and it is the dominant color. Orange Brittanys are more common, but liver is also commonly seen now. There is also a genetic tri color pattern, which is expressed even if there is only orange and white color (you just can’t see it). It’s only visible when there is liver color expressed. Which is interesting because it is written in our standard as “acceptable but not preferred” - but since it is often there whether seen or not, many people believe the standard should be rewritten.
It will be interesting to see these puppies when they are older to see if they resemble either breed more closely. So far, they lack the obvious spitz characteristics except for the tail, and so far as I can see, have zero Brittany characteristics at all - and interestingly neither are patterned at all. Solid colors don’t occur in either breed, although Kees puppies might not show as much pattern. So maybe it will change.
