Piebald
（重定向自Piebald skin）
A piebald or pied animal is one that has a pattern of pigmented spots on an unpigmented (white) background of hair, feathers or scales. The spots are pigmented in shades of black and/or yellow as determined by the genotype controlling the color of the animal. The animal's skin underneath its coat may or may not be pigmented under the spots but the skin in the white background is not pigmented.
