300 years ago, black was the color of the farmer and the lower-class samurai. It wasn’t exactly black but an indigo blue dyed so many times it’s close to black. The Samurai spirit is black. The Samurai must be able to throw his body into nothingness, the color and image of which is black. But the farmers liked black or dark, dark indigo, because the indigo plant was easy to grow, and the dye was good for the body and kept insects away.
