LOL, Brigdertrot! A hair follicle on steroids!
I parted the hair on that biggest white spot, and it does look like there is a tiny spot of pink skin there! Her skin is black, otherwise. It was pretty hard to tell for sure, though, without shaving her! And, no, I won't be doing that.
Maybe she's got some Paint in her, and that's all that showed up. LOL She does have Birdcatcher in her bloodlines way, way, back, though.
