- @blue - well, i need a bit more to go on with primrose
like what base coat she would be since it still plays a big factor even if she's white since the white gene is completely dominant [even double dominant black will be canceled out to white] if a horse has it.
the base coat may not be visible, but it still goes to the baby c:
if she was actually grey [which her picture kind of suggests since pure white often has white skin instead of black like the picture], then she would have been born a different color [like black or something] and eventually turned grey as she got older and can have dark colored babies who either stay dark or fade out to grey [dapple greys are often born dark and grey out]. grey can also be a carried gene where it doesn't show up on a parent but can in their offspring.
lipizzaner horses are actually born black/brown and become nearly pure white/grey as adults - not kidding
phantom looks to be a seal bay since he has lighter brown on his face and underbelly areas, that would make his genetics either EE/Ata or Ee/Ata depending on how dominant his black gene is, but he can carry some hidden genes like grey, cream, or pearl which can produce lighter colors like buckskins and palominos.
roan is a kind of tricky color since it has it's own gene [RR or Rr], but one of them could have a double recessive roan trait that doesn't show up physically so they could have a roan baby if you really want one. roans are often from roan parents though so i'm not very sure.
also that picture is technically bay roan since the bottom legs and mane/tail are all black with a brown base
this would be a red roan with red mane/tail instead of dark brown/black
wow so much writing lol cx
oh and i posted for amaera finally, she's grumpy and at the falls
