Many buyers pay a premium for bay and black horses, especially those with four white legs and white facial markings. Specific colours are often preferred over other physical traits, and some buyers even choose horses with soundness problems if they have the desired colour and markings. Sabino like horses are not preferred by buyers, despite one draught-breed writer theorising that they are needed to keep the desired coat colours and texture. Breed associations, however, state that no colour is bad, and that horses with roaning and body spots are increasingly accepted.
