Synthetic organic pigments, made as a by-product of coal tar distillation, were the result of progressive organic chemistry in the second half of the 19th century, followed by further developments and new inventions in the 20th century.
In industrial production, synthetic dyeing is superior to the old natural dyeing and replaces it, but it is relatively light resistant and not suitable for long-lasting paintings.

PERKIN's VIOLET was the first such dye (1856), and many dyes followed.
Until the 1950s, only three organic dyes, alizarin crimson, benzodiazepine blue, and benzodiazepine green, were recognized for persistent painting.
Coal tar extraction color and aniline color are commonly used pigments.
Since then, many synthetic pigments have been used in persistent painting.
