dun　　English　《color》

　 A somber brown color with a grayish hue.　Because this color implies a living thing, it could be the most important color in fly tying.

　 Importance is given to the delicate differences in the color and its lightness, and each carries a name.　The color of similar tones and lighter ones are blue dun, light blue dun, and dark blue dun.　The color of similar tones and darker ones are rusty dun and iron blue dun.　There are also honey dun, sandy dun, and chocolate dun, and they differ slightly from the ordinary dun.　It appears the word "dun" originated from "donn", the Irish or Gaelic meaning given to a color similar to brown, or "dwn", the Welsh meaning given to a somber brown color.

　 Many mayflies are called "XX Dun," and the author believes that a color called XX dun existed first, and the mayfly later came to be called such when its wings turned into XX dun color.
