Orcein
Once used as a food colouring but now banned throughout the EC Cudbear is a dye extracted from orchil lichens that produces colours in the purple range. It can be used to dye wool and silk, without the use of mordant. Cudbear was the first dye to be invented in modern times, and one of the few dyes to be credited to a named individual. Orcinol is extracted from archil lichen, Rocella tinctoria. It is then converted to orcein by ammonia and air. Orcein is a reddish-brown dye, orchil is a purple-blue dye. Orcein is also used as a stain in microscopy to visualize elastic fibers,Hepatitis B surface antigens and copper associated proteins. It is a mixture of phenoxazone derivates - hydroxyorceins, aminoorceins, and aminoorceinimines.
