Read the text below: The color mauve
In 1856 the chemist William Perkin was trying to find a cure for malaria when his experiments produced a dark sludge.
It was a disappointing result, but Perkin noticed the color. It was a particular shade of purple, which happened to be a hot color at the time. He was able to isolate the compound that produced the color – mauve – and realized it worked well as a dye. Within a year, Perkin patented his synthetic dye, the first synthetic dye ever made, and opened a company to make and sell it.
