Mauveine
A purple dye first made by accident in 1856, launching the synthetic dye industry
No single value: Mauveine is a material, and its colour varies. The background shows its family, purple and violet.
Mauveine is a synthetic purple dye discovered in 1856 by William Henry Perkin while he was trying to make quinine. It became the first mass-produced chemical dye and caused a fashion craze in the late 1850s, but was soon replaced by newer colours.

- First synthetic dye to be mass-produced
- Started a brief but intense fashion craze for purple
- Made from aniline and toluidine chemicals
- Linked to health risks for dye workers
What colour is Mauveine?
Mauveine is a synthetic dye that produces a purple shade, once called aniline purple. It stands out for being the first of its kind made from chemicals rather than natural sources. The colour is a soft purple, similar to the mallow flower, and was once highly fashionable. It differs from earlier dyes by its chemical origin and the intensity of its colour.
Where does Mauveine come from?
William Henry Perkin discovered mauveine in 1856 while attempting to create quinine, a treatment for malaria. The dye was first called aniline purple, then mauve, after the French word for the mallow flower. Its popularity in fashion was brief but intense, sparking jokes and cartoons about its spread. The dye industry that followed changed both chemistry and medicine.
How is Mauveine made?
Mauveine is made by combining aniline, p-toluidine, and o-toluidine in acid and water, then adding potassium dichromate. This process creates a mix of related chemical compounds, each with slight differences in structure. The exact arrangement of atoms in mauveine was not fully understood until the late 20th century, with more variants identified over time.
Where Mauveine is used
The dye was first used to colour silk and other textiles, quickly becoming a fashion trend in the late 1850s. Later, it was also allowed as a food colouring in the United States under various names. Its use in industry revealed health risks for workers, but the synthetic dye industry it started led to advances in other fields.

In Holy Week, members of religious brotherhoods walk in procession in robes and pointed hoods, many of them purple, the colour of penance. A purple band also marked the flag of the Second Republic.

Mauveine is not a single compound but a group of related chemicals, including mauveine A, B, B2, and C. Each has a slightly different arrangement of methyl groups. Over time, more forms were discovered, and similar dyes like safranine were shown to be related.
