1914, 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" (see fallow (adj.)). The horse so called because of its dove-like coloring, light brown or cream with a pale mane and tail.[palomino etymology, palomino origin, 英语词源]
