...And it looks like a pea comb to me from the photos. I think I see a main line of peas then very small ridges on both sides of the main pea line.
It is definitely not a rose comb...or at least what I'm used to seeing develop....that will look like a little horseshoe with indent in the middle that grows on the edges with a little knob at the top (often but not always).
Which, keep your fingers crossed, could mean she got the blue gene and might provide an olive egger as it would be over a dark layer.
