noun
buckskin (horse color)
Refers to a horse coat color: tan or yellowish body with black points (mane, tail, lower legs). A specific equine color term.
あの川原毛の馬はとても美しい。
That buckskin horse is very beautiful.
川原毛は日本ではあまり見かけない毛色だ。
Buckskin is a coat color not often seen in Japan.
The derivation is uncertain. The kanji 川原 (riverbed) and 毛 (hair) may evoke the color of dry riverbed sand, but this is speculative.
