Hi! So i random-shuffled this clean girl and managed to get both a rare brown rosette in slot 7 and black pelage in a new slot— slot 8

i guess im wondering a) what would her cubs with the black pelage be worth?
b) should i be studding her to kings that have all BO markings? would my king's applicator markings make her black pelage cubs be worth less?
and c) do any slot breeders even want black pelage? i know one person contacted me with interest after i was like ay a rosette, but im not sure if its a common interest? im not a slot breeder so i don't know haha

thanks sm for your time!
