What color is typical for a Grullo horse?

A Grullo horse typically exhibits a unique coat color that can be described as mousy or smoky. This coloration is characterized by a grayish hue with a dilution of the black gene, which gives the horse its distinctive appearance. The coat usually varies from a light mouse color to a darker slate, often with a distinct dorsal stripe and limb markings. This combination of colors and markings is what sets Grullo horses apart from other color patterns.

The other choices represent different horse colorations that do not accurately describe the Grullo. Reddish and copper-red refer to chestnut or sorrel colors, while blue-black implies a solid black horse. The defining feature of a Grullo’s coloration lies in its smoky or mousy appearance, making it easily identifiable among other horse colors.
