Tumeric is from the ginger family and native to Southeast Asia. The rhizomes of the plant are gathered, boiled and dried to produce a spice used in cooking. The bright yellow powder can also be used as a fabric dye by dissolving it in hot water. The depth of color can be controlled by the amount of tumeric used.
The fabric will be bright yellow if dyed with tumeric. However, by then dipping the fabric in a solution of lye and water, the fabric will turn a deep orange or red.
