| Uemura's notes | Normally, the dye bath with this plant should be kept warm, but boiled. If the bath is boiled, the resultant color would shift toward black, which would be similar to the one exposed to larger quantity of ash water mordant bath. Dark purple named "Kuromurasaki ()" was noted in the Nihonshoki (), and "Keshimurasaki ()" was in the Engishiki (). The Kuromurasaki would not have been produced in this method. Dyeing paper in Keshimurasaki was recorded in historic manuscripts from the Tempyo () period (729 -749 AD), Japan. |
