What coloration is characteristic of the mane and tail in a Dun horse?

The coloration characteristic of the mane and tail in a Dun horse indeed varies widely, which includes options such as black, brown, red, or even white. The Dun coat is known for its dilute coloring that typically results in shades ranging from gold to cream. However, the mane and tail color does not have to match the body color and can present a variety of colors. This characteristic diversity is an important point that defines the breed, as it allows for individual variation among Dun horses, setting them apart from other equine colorings that might have stricter requirements for mane and tail colors. The other options are too restrictive or specific, failing to capture the range of possibilities that exist for Dun horses' manes and tails.
