Neither parent look bay or brown IMO. That leaves them either as black or red. If the baby is a double dilute, then the parents would have to be either smoky black or palomino, and neither of them look palomino. So narrowing it down to them being smoky black, they cannot produce a perlino foal. Ergo, baby, if a double dilute, must be either cremello or smoky cream, and given the dark colour, cremello is probably not the case.
If the foal is a double dilute, then both parents have to have the cream gene to pass on, as a double dilute has two copies of the gene. So yes, if the foal is a smoky cream, then the sire and dam are both smoky black.
Ok, thanks. So, when I did the color calculator it gave a percentage probability of my buckskin tobiano mare and this same stallion producing a perlino. She obviously carries cr because she's a buckskin, and if he is smoky black then there's that. Does that sound correct?
