1.
copper color; bronze color
A warm, reddish-brown color resembling polished copper. Used to describe skin tanned by the sun, metallic surfaces, or autumn foliage.
銅 is a classical Japanese word for copper (literally "red metal"), in contrast to the more common modern reading 銅. The compound 銅色 has a literary and evocative quality. It is often used to describe well-tanned skin (銅色の肌) and conveys a warm, healthy, outdoorsy image. The more colloquial equivalent would be 銅色, though あかがねいろ is preferred in literary or descriptive writing.
