Is the African ancestry in them visible? Their mother is a mixed Brazilian.

They look mixed (third option) but if you didn't show me their mother I might start thinking that they are white, complicated I guess. They're going to be ''of colour'' when they grow up but either way that's not important for me or for them surely too.
