This is from one of my books on quill work. This is supposed to be from original recipes that would have been used before 1830, as that is the time that the Indians started using commercial dyes brought in by the euro-pean traders.
Red dye was made from:
Blood root
Sassafrass
Red Bedstraw
Alder
Buffalo berry
Puccoon (Lithospeermum carolinense)
Red Osier Dogwood
Wild Plum
Choke Cherry
Hemlock
Red Cedar
Mordants:
Birch
Oak
Iron oxides
Nut Galls
Sumac
Alder
Black Oak
Ashes
Alum
Vinegar
Dock--female
Dye Formula for quills. I would think that if you could dye quills, you could dye anything that would take dye.
1. Blood root and alder inner bark mixed in equal parts and boiled in water. Add alum. Simmer quills in resulting liquid until desired shade is reached.
2.Two parts blood root, one part alder, one part red osier dogwood, one part choke cherry. Boil for quite awhile then steep quills in the hot liquid.
3.Nine inches of puccoon root boiled in one quart of water. Soak quills in hot water and then simmer in dye for half an hour and let set overnight. May be re-dyed to get desired shade.
4.Scrape the outer bark off of hemlock root and boil the rest with alum added. Soak the quills in the hot liquid. Grindstone dust may be used instead of the alum.
5.Boil the bark from oak, white birch, and red osier dogwood. add two cups of cedar bark ash to the liquid and boil again. Strain the liquid and add previously soaked quills.
6.Buffalo berry or squaw currents boiled in water with female dock root. Steep quills in hot dye bath. Alum may be added.
7.Red bedstraw boiled in water with alum. Quills are steeped in the dye bath. Re-dye the quills until the desires shade is reached.

Let us know if you try these and if they work. Purples were done with Blackberries and alum. Apparently alum was naturally available as they refer to it as allum. It was imported from England in the early 17th century as a mordant for dyeing wool.
