The specialized term paint refers specifically to a breed of horse with American Quarter Horse or Thoroughbred bloodlines in addition to being spotted, whereas pinto refers to a spotted horse of any breed. Americans usually describe the colour of a pinto literally: black-and-white, chestnut-and-white, or bay-and-white.
