What is the general classification for a horse with a coat pattern containing large amounts of white?

The classification for a horse with a coat pattern containing large amounts of white is referred to as pinto. This term describes horses whose coats are marked with large patches of white and any other color, which can include various shades such as brown, black, or chestnut. Pinto horses have a distinctive appearance that is characterized by their bold and prominent color patterns, making the large areas of white easily recognizable.

The pinto classification encompasses different types of patterns, which can include specific arrangements of color and white. This classification can be found in many horse breeds, as it is based more on coat pattern than on breed itself.

The other terms, while related to coloration, describe different patterns or types that don't specifically apply to the broad categorization of a horse with significant white. For example, splashed generally refers to a specific pattern where white seems to splash up from the lower body, Appaloosa describes a breed known for distinctive spots and mottled skin, and overo refers to a specific pattern where white does not cross the back of the horse. Thus, pinto is the most inclusive and general classification for horses with extensive white patches on their bodies.
