What general term is used for horses that exhibit extensive white markings on their bodies?

The term "pinto" is used to describe horses that have large patches of white alongside another color, resulting in extensive white markings on their bodies. Pintos can come in various color combinations, but the defining characteristic is the presence of these large white areas. This contrasting pattern is distinct from other color terms, as it specifically refers to the coat pattern rather than a solid color or a shade like palomino or chestnut.

In contrast, roan refers to a coat pattern characterized by a mix of white and colored hairs, which typically results in a coat that appears to have an overall color with a sprinkled effect rather than extensive white markings. Palomino and chestnut are terms that refer to specific coat colors. Palomino describes a golden coat with a white mane and tail, while chestnut refers to a reddish-brown color. Neither of these terms encompasses the pattern of extensive white markings that define a pinto. Thus, pinto is the most appropriate term for horses with significant white markings.
