Here are some other common colors:
* Dun: This is the most common color, characterized by a base coat of golden or yellow with a dark dorsal stripe running down the back and often stripes on the legs.
* Bay: A reddish-brown color with a black mane and tail.
* Black: Solid black, but often with a hint of brown in the sun.
* Brown: A lighter shade of brown, often with a lighter mane and tail.
* Grey: A silver or white color with darker points (mane, tail, legs).
* Roan: A mixture of white hairs throughout the coat, giving a speckled appearance.
It's important to note that these colors can vary in shade and intensity, and some Highland ponies may have unique color patterns or markings.
