After synthetic pigments and dyes such as alizarin were invented in the late 19th century, natural-dye production gradually diminished.

Madder root extract is red because the alizarin it contains reflects wavelengths that correspond to red and absorbs all other wavelengths.

Madder was a dye of commercial importance in Europe, being cultivated in Holland and France until the market collapsed following the development of synthetic alizarin dye in 1869.

- An orange-red crystalline compound used in making red pigments and in dyeing

- A type of red or crimson dye
- A reddish purple pigment obtained from the root of the madder plant. Combined with salts of metals it creates the lake colors.
- A bright red synthetic dye; made into a pigment, alizarin crimson (synthetic madder lake), by laking (binding to an inert powder). Alizarin is one of the coloring components of the natural dye madder.
