It's not possible to get tricolor kits from a black tort holland to a vm black tort holland. Tortoise is recessive to harlequin, and solids can't produce a broken (tricolor is just broken harlequin). Two black tort hollands can't make a frosty (its called frosty in hollands, never ermine); frosty is an agouti color and two selfs (torts) cant make an agouti. Breeding an orange to a tort, and frosty is possible if both parents carry it. If both torts have frosty in their bloodlines (and carry it, unless the frosty is a parent there is a chance its in their pedigree but they dont have the genetics for it) then you CAN get sable points (/sallanders) however
