Grulla is a captivating coat color found in horses, characterized by its unique slate gray hue. This color results from the dilution of a black base coat by the dun gene. There are indeed different shades of grulla, each offering a distinct appearance while maintaining the core characteristics of the grulla color.
What Are the Different Shades of Grulla?
Grulla horses exhibit a range of shades, from light to dark, all sharing a smoky gray tone with a distinct dorsal stripe and primitive markings. Here are the primary shades of grulla:
- Light Grulla: This shade features a pale, silvery-gray coat with subtle primitive markings.
- Standard Grulla: The most common shade, showcasing a medium gray color with clear primitive markings.
- Dark Grulla: A deeper, almost charcoal gray hue that highlights the dorsal stripe and leg barring.
How Does the Dun Gene Affect Grulla Color?
The dun gene is responsible for the dilution of the black base coat, resulting in the grulla color. This gene also introduces primitive markings, such as:
- Dorsal Stripe: A dark line running down the spine.
- Leg Barring: Stripes on the legs resembling those of a zebra.
- Shoulder Stripe: A faint stripe across the shoulders.
These markings are essential for identifying a true grulla horse.

How Do You Breed a Grulla Horse?
To breed a grulla horse, you need at least one parent carrying the dun gene. Breeding a black horse with a dun horse increases the likelihood of producing a grulla foal, but genetics can be unpredictable.
What is the Cost of a Grulla Horse?
The cost of a grulla horse varies based on factors such as breed, age, training, and pedigree. Generally, their rarity and unique appearance can command higher prices compared to other coat colors.
