Historically, what terms were used to describe horses with pinto coats?

The terms "piebald" and "skewbald" have been historically used to describe horses with pinto coats. Piebald refers to horses that have a coat with large patches of black and white, while skewbald describes horses that have white combined with any other color aside from black. These terms are well established within the equine community and provide a clearer understanding of the varying types of pinto patterns and colors.

In contrast, the other options do not accurately represent the terminology specific to horses with pinto coats. "Dappled and striped" refers to different patterns that involve spots or stripes rather than the specific color combinations associated with piebalds and skewbalds. "Solid and patterned" is too broad and does not capture the nuances of the pinto patterns. Similarly, "white and colored" lacks the specificity needed to describe the unique pinto coloration accurately. Thus, piebald and skewbald are the correct historical terms associated with pinto horses.
