Traditional Japanese colors (Washoku)are adelicatesystemof hues that have been named since ancient times after Japan’s natural landscapes, the changing seasons, and the flora and fauna of the country. From the elegant colors cherished by the aristocracy of the Heian period to the subdued shades popularized by the common people of the Edo period—such as the “48 shades of brown and 100 shades of gray”—a diverse range of colors has evolved alongside the historical context.

Historical Color Classification

- Forbidden Colors (Kinji): Colors that were not permitted to be worn by anyone other than those of a specific rank. In particular, the Emperor’s Koro-zome (a type of yellow dye) is still considered an “absolutely forbidden color” today.
- Forty-Eight Browns and One Hundred Grays: These are a diverse range of intermediate colors that emerged during the Edo period when the shogunate’s prohibition on luxury goods banned flashy colors, leading commoners to enjoy subtle nuances within shades of brown and gray.
