What is "Kōshoku"? Origin and etymology

Kouiro, as the name suggests, is a color name derived from the fact that it was dyed with fragrant wood. The main dyes used were said to be the bark and resin of fragrant trees such as cloves, agarwood, and aloeswood. Cloves, in particular, are a spice made from the dried buds of a plant in the Myrtaceae family and have been highly valued as a dye since ancient times. Because these fragrant woods were extremely precious and expensive, Kouiro was considered a color that symbolized people of high social standing.

In reality, cloves were used as the main dye, and subtle shades were adjusted by combining them with other dyes such as Japanese safflower and madder.

Historical background of incense color

Incense color was extremely popular among the aristocracy during the Heian period. The nobility of the time had a custom of infusing their clothes with incense, and clothing dyed with incense wood in this color exuded elegance through both its fragrance and color. It frequently appears in literary works such as "The Tale of Genji," where it is depicted as the color of clothing worn by noble figures. Because incense wood was also used in Buddhist rituals, this color is believed to have also carried religious connotations of purity and sanctity.

During the Edo period, due to the influence of sumptuary laws, subdued brown tones became popular, and the color of incense became widely known to the general public.

Related literature, waka poetry, and seasonal words

Incense color is known as one of the important colors that adorn Heian literature. In "The Tale of Genji," many characters, including Hikaru Genji and Murasaki no Ue, are depicted wearing incense-colored clothing, suggesting their nobility and high level of education. In particular, in the "Plum Branch" chapter, the color appears in clothing related to incense during the incense-matching ceremony.

Furthermore, Sei Shonagon's "The Pillow Book" also contains descriptions such as "fragrant-dyed robes," suggesting how sophisticated the color of incense was treated in the court culture of the time. While the color of incense itself is not a seasonal word, its ingredients and the culture of its fragrance have been celebrated in the world of waka poetry as a theme symbolizing elegance and refinement.
