Here's why:
* Horses in History: We have limited details about the specific horses owned by historical figures. Records often focus on battles, lineage, and political events.
* Color Variations: Horses can have a vast array of coat colors and patterns. While a black and white horse is possible, it's not a common color combination.
* Henry IV's Reign: Henry IV ruled England from 1399 to 1413. Horses were a significant part of warfare during this period, but specific horse colors weren't often documented.
It's likely that Henry IV owned a variety of horses, but we don't have definitive information about their colors.
