Who invented dye?

William Henry Perkin in 1856.

The use of dyes dates back to ancient times, and people have been using natural materials to color fabrics and other materials for thousands of years. The exact origins of dyeing are difficult to determine, and it is likely that the discovery of dyes occurred independently in different parts of the world.

Some of the earliest known examples of dyed fabrics come from ancient Egypt, where people used natural dyes made from plants and minerals to color their clothing and other textiles. In ancient Mesopotamia, people used dyes made from insects to produce shades of red, purple, and blue. In ancient China, people used dyes made from plant and animal materials to produce a wide range of colors.

Over time, people developed new methods of dye production and discovered new sources of dyes. The development of synthetic dyes in the 19th century revolutionized the dye industry and led to the widespread use of dyes in many different industries. Today, dyes are an essential part of many products and are used in a wide range of applications.
