What is the correct term for color of a red horse?

There's no single "correct" term for the color of a red horse. It depends on the specific shade and how it's described. Here are some options:

Basic:

* Red: This is the most common and general term, but it's not very specific.

* Chestnut: This is often used for a horse with a rich, reddish-brown coat.

More specific:

* Sorrel: A lighter, more golden shade of red.

* Liver chestnut: A very dark chestnut, almost brown.

* Bay: A horse with a reddish-brown body and black points (mane, tail, lower legs).

* Brown: A very dark shade of chestnut, sometimes with a slightly bluish tinge.

Other:

* Red roan: A red coat with white hairs mixed in.

* Palomino: A horse with a golden coat and a white or cream mane and tail.

Important Note: It's always best to describe the horse's color as specifically as possible to avoid confusion. If you're unsure about a specific shade, a professional horse person or veterinarian can often help.
