The pinto is either Tobiano or Overo pattern or a combination of both known as Tobero, and there is also Sabino.
Below are the descriptions of these patterns and illustrations.
The Tobiano Pinto is basically a white horse with patches of colour. It generally has white legs and white crossing the backbone. The head, chest, flank, buttock and often the tail are the usual coloured areas.
These are some variations of the tobiano pattern from minimum colour through to maximum colour.
The Overo Pinto appears as a dark horse with white marking. These markings are of irregular shape with jagged edges and normally originate on the horses side or belly, often spreading towards the neck, legs and back. Colour appears to frame the white areas. An Overo usually has a dark mane, tail, legs and backbone. Bald or white face often accompanies the Overo pattern.
These are some variations of the overo pattern from minimum colour through to maximum colour.
Horses which show definite characteristics of the two marking patterns described with the Tobiano and Overo are referred to as Tobero.
