There is one more experiment I wanted to try to get black: using dye extracts with no indigo. It wasn’t particularly successful on wool. The best black is equal parts logwood grey (logwood with iron) and Himalayan Rhubarb. The ones with madder are too red. That might work better with larger quantities of fiber. The test fibers are the same as in the previous black post.

From top to bottom
Logwood grey + Him. Rhubarb, equal parts
Logwood + Him. Rhubarb, equal parts
Logwood Grey 2 parts, Him. Rhubarb 1 part, Madder RT 1/2 part
Logwood 2 parts, HR 1 part, Madder RT 1/2 Part
Logwood Grey 2 parts, Osage Orange 1 part, Madder RT 1/2 part
Logwood 2 parts, Osage Orange 1 part, Madder RT 1/2 part
