1866: Methyl Violet 1868: Synthetic Madder called alizarin 1872: Methyl Green – still in use today 1873: Sulpher Brown (Photo: 1868 American dyed indigo – natural)  

..  includes the new “indigo” which is used for blue jeans today.  Most of the aniline dyes were named for war skirmishes in Europe. 1858: magenta by Vergoon 1861:  Methylviolet by Lauth 1862:  Hofmann’s Violet 1862: Bismarck Brown by Martus and Lightfoot – the first water soluble dye 1863: Black …

..a few Scottish tweed manufacturers were using exclusively natural dyes in commercial processes.  With the synthetics and mass production of the Industrial Revolution, a rising middle class in particular were wanting the affordable and rich colors of the aniline dyes.

.. was there was a rise in interest in chemistry in the 1870’s.  Perkins, who had accidentally discovered the mauve dye “mauviene”, had his own London factory to produce it.  From 1858 until the early 1900’s, magenta or fuchsine – two other purplish blue colors – had patents constantly revising …
