What is the color reddish-brown? Origin and etymology.
Shakudō-iro refers to a dark, reddish-brown color. Its name originates from "shakudō," an alloy of copper with a few percent of gold added. When this alloy is treated with a traditional coloring technique called "ni-iro," which involves boiling it in a special solution mixed with verdigris and copper sulfate, it develops a beautiful, slightly purplish black color, reminiscent of a raven's wet feathers. This unique color and metallic texture are the origin of the name shakudō-iro.
A key characteristic is that these are not simply pigments or dyes, but color names that originated from metalworking techniques.
A historical background of reddish-bronze
While the technique of using shakudo (a copper alloy) can be seen in artifacts unearthed from the Kofun period in Japan, it is believed that it was only after the Muromachi period that it became refined as a craft and widely used. In particular, it was frequently used for sword fittings such as tsuba (sword guards), kozuka (small knives), and menuki (ornaments on sword fittings), and was highly valued as a material symbolizing the status and aesthetic sense of samurai. In the Edo period, due to its luxurious feel, it was also used for decorative items such as inro (small containers for carrying medicine), netsuke (miniature sculptures), and kiseru (pipes), and became popular not only among samurai but also among wealthy townspeople.
It is believed that this color name became widely established along with the popularization of such crafts.
Related literature, waka poetry, and seasonal words
Because the color reddish-brown originates from metalwork, it rarely appears directly as a subject in waka or haiku poems that describe natural landscapes. However, in literary works, especially historical novels, the name can be found when describing the possessions and furnishings of samurai. Descriptions such as "a reddish-brown tsuba (sword guard)" or "metal fittings made of reddish-brown" are used as effective expressions to convey the weight and prestige of the item or the high status of its owner.
Although it is not designated as a seasonal word, its deep, subdued colors evoke the heavy, somber atmosphere of late autumn or winter.
