Isabelline — If you work with animals—particularly birds or horses—you may have heard the name “isabelline” before. Isabelline is often used to describe the coats of horses or the feathers of birds, although it has also been historically used to describe clothing and dates all the way back to the year 1600. It belongs to the off-white, neutral, or beige family, and is commonly known as Isabelline. It is a soft, pale, and lightly tinted shade that offers a subtle, timeless elegance.
