 In North America and England, natural-colored Romneys (whose fleeces are not white, but black, gray, silver, variegated) have come to be valued for what they bring to hand-spinners and weavers who like the palette of natural colors.Traditionally, natural-colored (or “black”) sheep were detested, as even a small amount of black fiber on an otherwise white sheep can ruin hundreds of pounds of textile.Since 1972, natural-colored Romneys have been registered with the American Romney Breeders’ Association (founded 1911), which has developed a special breed standard for them.
