What color is commonly associated with Buckskin horses?

Buckskin horses are characterized by a specific coat color that is a yellow or gold shade, typically accompanied by darker mane, tail, and sometimes leg markings. This coloration resembles that of a buck deer, which is where the name "buckskin" originates. The combination of this yellow or gold body color with black points (mane, tail, and lower legs) is a distinguishing feature of buckskin horses, making them easily identifiable.

This description aligns closely with the correct answer, emphasizing how the unique coloration defines a buckskin horse's appearance. The other options do not accurately capture the specific traits that define a true buckskin coat, such as the lack of the black points or the different base colors mentioned.
