Synthetic Dyes
Organic compounds are used to create synthetic colours. Prior to the discovery of synthetic dyes in 1856, dyestuffs were made from natural materials such as flowers, roots, vegetables, insects & minerals. Natural dye batches were never same in colour and intensity. Using computers and computer colour matching (CCM), colour is produced that is same from batch to batch.
History
An eighteen-year-old English scientist named William Henry Perkin was looking for a malaria remedy, a synthetic quinine, when he accidently produced the first synthetic colour. He discovered that aniline oxidation could colour silk. He created a reddish purple pigment from a coal tar derivative. Mauve was the name given to the bright purple. The dye was not resistant to sunshine or water and faded quickly to the hue now known as mauve, a faint purple. This finding prompted more study with coal tar derivatives and other organic chemicals, resulting in the birth of a whole new industry of synthetic colours.
