Uemura's notes When rubbing fresh flower petals of the rose on a fabric, the resultant color was blue purple. And by mordanting this with copper, the color became red purple. This was considered to be due to its weak acidic condition, rather than the presence of copper. The dye compound was fixed well to the fiber.
