Both females in the photos are snow corns. They are sisters and one is quite a bit more pink than the other. The one in the lower pic has more yellow coming into her background color. It typically starts on the chin and along the neck and gets darker with age. Our male snow is quite a bit pinker (photo below) and adult snows tend to have a whitish background, but the saddles can vary through ivory, cream color, yellowish, greenish, pink or pink with greenish edges.
