What is the traditional Japanese color "Yoshioka dye"?




Yoshioka dye is a black color with a slight brownish tinge, a traditional color that originated in the early Edo period. It is said to have been invented by Yoshioka Kenpo, a swordsman and military instructor for the Ashikaga Shogunate, based on a dyeing method he heard from his disciple, the Ming dye man Li Sanguan. The method is recorded in the Konya Chasome Kudensho (1666), and involves dyeing with a liquid made from the peels of bay laurel, then applying an iron mordant to create a dark brown color.





Yoshioka dye = Yoshiokazome

 

Yoshioka Kenpo was a man of many talents, skilled not only in swordsmanship but also in dyeing. Yoshioka dye, which bears his name, is said to have permeated the lives of ordinary people as a practical and subdued black, and to have been loved for generations to come. "Yoshioka dye" is pronounced "Yoshioka-zome."
