Aniline dyes were first synthesized around 1856. The first aniline dye, known as Perkin's Mauve (Tyrian Purple), was discovered by English chemist William Henry Perkin. This breakthrough in organic chemistry paved the way for the production of a wide range of synthetic dyes, which were cheaper and more colorfast than the natural dyes that were previously used. Initially, aniline dyes were available in a limited range of colors but by 1859 "hotpink" (magenta and solferino/fuscia) was fashionable, and others "from 1860, and in the '60s by various shades of brown, violet, blue, green, yellow and black". https://www.npg.org.uk/collections/search/portrait-list.php?.... |
