North America has more pinto variation than Britain, at least historically.
A piebald is black Tobiano and a skewbald is other color Tobiano. There are no traditional terms in British horsemanship for Frame Overo (mutation evolved in USA) or sabino. There is an old word for the splash pattern common to Clydesdales I think it’s blagdon?
North America has a higher population of pinto patterns in mustangs, stock horses, and even saddlebreds that get sabino. Genetic testing to distinguish pinto genes and their expression is recent, developing, and not fully understood.
Distinguishing between Frame Overo and other pinto genes is crucial because Lethal White Syndrome.
Pinto is the Spanish word for Paint, and the two were used interchangeably until the 1960s when the Paint registry was set up to capture quarter horses refused registration because they had too much white.
I don’t see why any of this would be obvious or even of interest to a non horse person, indeed many good riders I know who came up via h/j or pony club are clueless, and not even interested in understanding pinto genetics.
We nevet talk about “a knight on a grey horse,” after all.
