That is really weird! Are the black marks graying? Or are they staying the same shade?
Grays, gotta love them!
That's weird about Lacey! But possible. Her dad was a 1970's model so I guess he definitely could have been super dark brown and mistaken for a fading black... Or there's always Lacey's mom, but who knows anything about that lady.
All I really know is that Lacey started out dark enough to look "like she had been covered in lace and spray painted black" (that's what her previous owners told me about how she got her name... )....
Brown could definitely be a possibility.
