I think for anybody reading this thread and looking for a natural dye, they might want to double-check on what plants are available for the area that they are portraying or , geographically located. Meaning if one is say in England or Germany (where a few of our members reside), but are portraying a fellow of the Shenandoah Valley, one might want to research what was available to folks in that valley..., or wherever one is "from", plus what was available in trade. So Bamboo or avocado, or pomegranate might not be good ideas for dyes for an outfit from the 18th, or even first half of the 19th century.
check on mordant's too, as one of the links shows hanks of multicolored
wool..., and as any of the craft dyers will tell you, wool works one way with some dyes, linen another, and cotton another. :wink:
Madder commonly was imported from Asia, and gave a brick-ish red color BUT..., a lot of it today comes from Afghanistan, AND it's a root that gives a redder dye the longer it is aged. The war in Afghanistan caused a lot of madder-root to sit in storage until the owners felt it safe to return home, so NOW what one gets when ordering Madder-root for dying from eBay is stuff that produces a deeper red, with a bit more pink in some cases. Not quite the color one needs. :shocked2: It was a preferred red because it was cheap, so was used for the fabric on British enlisted soldiers' coats.
Cochineal was also a popular though expensive red dye in the 18th century. It gives a scarlet color, and was used for British officer's uniforms.
Green as mentioned in a previous post, does come from indigo followed with yellow, BUT indigo dying is a rather elaborate process beyond simply dipping the cloth in a dye bath, or dipping the cloth in a mordant, followed by the dye bath. There are some sources for indigo that have been partially processed so one may find it easier to do.
Here's another link on dyes, but it gives some information as to the sources most often used by Native Americans, which may be a clue as to which natural dyes were most commonly found.
USDA/US Forestry Service: Native Plant Dyes.
