According to the Book of Cloth, sorghum rice (rice husk) is the main dye, and hematoxylin is the supplement. The ratio is 3: 1, and no mordant is used. According to this dosage, the color should be light, a little white and pink.

In the book of cloth, only the amount of dye is written, but the specific dyeing process is not written, so it is difficult to judge its accurate color depth. After all, besides the amount of dye, dyeing time and temperature are also important.
