In industrial production, synthetic dyeing is superior to the ancient natural dyeing and replaces it, but it is relatively weak in light resistance and is not suitable for lasting paintings. Perkin's Violet was the first such dye (1856), and many dyes followed. Until the 1950s, there were only three kinds: alizarin dark red, benzene dimethyl blue and benzene dimethyl green Organic dye It is recognized that it can be used for persistent painting. Coal tar extract color and aniline color are commonly used pigments. Since then, many synthetic pigments have been used for persistent painting.
