Were there dyes in ancient times? What did ancient people use as dyes?

In ancient China, there were two kinds of materials that could be used for coloring. They are mineral pigments and plant dyes respectively, but plant dyes are the main dyes in ancient times. Ancient people knew and mastered many characteristics of plant dyes very early. When dyeing, pigment molecules in plant dyes are immersed in fabric fibers, thus changing the color of the fibers. This color dyed by plants will not fall off easily after sun exposure and water washing, and some will not even fall off. Pigment and fiber have been integrated.

In ancient China, the dyeing process mainly used plant dyes. From the Zhou and Qin Dynasties, a large number of plant dyes were produced and consumed, and exported abroad in the Ming and Qing Dynasties. There were many plant dyes in ancient times, and the quantity was also very large. According to the characteristics of various dyes, many dyeing processes have been produced: direct dyeing, vat dyeing, mordant dyeing and anti-dyeing. The varieties of dyes are complex and diverse, and the process methods are countless. Their combination resulted in the diversity of ancient printing and dyeing industry and rich chromatography. There are hundreds of chromatograms recorded in the ancient books of princelings' children, especially one color tone, which can clearly distinguish dozens of similar colors to meet various needs. However, it is necessary to master the formula combination of various dyes and change the process conditions, which can only be done by being very skilled.
