What is "Aitetsu"? Origin and etymology
The name "Aitetsu" (藍鉄) literally means "indigo blue" and "iron blue," and its origin lies in this color, which is a combination of "indigo" and "iron." Specifically, it refers to a dark, iron-tinged blue-green color achieved by applying an iron-containing mordant (such as iron plaster) to a particularly dark indigo dye, adding a blackish tint. This process increases the depth and richness of the color compared to regular indigo, creating a complex and subdued hue that resembles a greenish-blue or bluish-gray. It is one of the colors that symbolizes the refined aesthetic sense of Edo.
Historical background of Aizute
The color name "Aitetsu" (藍鉄) is believed to have become commonly used from the mid-Edo period onward. At that time, the use of flashy colors was restricted by the shogunate's sumptuary laws, so commoners found subtle differences in shades of muted colors such as brown and gray to enjoy fashion. Aitetsu is thought to be one of the colors that emerged during the fashion trend known as "Forty-eight Browns and One Hundred Grays." It was used in samurai formal wear, townspeople's everyday clothes, and shop curtains, and its subdued and calm hue was favored as a symbol of "chic" or "stylishness."
Related literature, waka poetry, and seasonal words
Because "ai-tetsu" (藍鉄) is a relatively new color name, it rarely appears directly in classical literature or waka poetry from the Heian or Kamakura periods. However, many kimonos reminiscent of this color can be seen in ukiyo-e prints from the Edo period. In particular, in actor prints depicting Kabuki actors and genre paintings depicting the daily lives of townspeople, a color close to ai-tetsu is used for the kimonos worn by the characters. This suggests that this color was widely popular among people at the time.
