Yeah that's called gypsy face, as for color.. brown red is a hobby name for gold birds in the birchen pattern. Birchen is used for both the gene and also the silver birds with this gene. Confusing I know.... even worse, sometimes brown reds are called gold birchens. Sigh. If the brown is present over most of the body, chances are she has the birchen gene.
what comb does that blue have? if pea, then she could be single dose NN.. the blue could have come from the white hen, just couldn't her genetic color(s) due to the white gene masking everything else she has.
Be a little careful about claims of never producing non NN.. for example a double dose rooster over a flock of entirely non-NN hens would produce 100% NN chicks. I've seen groups with some birds obviously single dose(or even some non NN) in both sexes and the owner claimed they never produced full feathers.. I just smile and nod..... stick with picking out chicks with no or tiny bowties and you should be good.
