palomino (n.)

"horse with a light brown or cream coat and a pale mane and tail," 1899, (earlier palomino horse), from American Spanish palomino "cream-colored horse," from Spanish, literally "young dove," perhaps from Italian palombino "dove-colored," from Latin palumbinus "of wood pigeons," from palumba "wood pigeon" (from PIE root *pel- (1) "pale"). The type of horse was so called because of its dove-like coloring.
