Isabelline, also called Isabella, is a light fawn, light cream-brown, or light parchment color. It is found in the coloring of animal coats, especially in the feathers of birds and, in Europe, horses. The word’s origin is unknown.
Fashion has historically used it as well. The word was initially recorded in print as “isabella color” in 1600; once “isabelline” was published in 1859, this use eventually started to be used interchangeably in the literature.
Some Italian Greyhounds have coats described as isabelline in color.
