The roots of this ancient dye plant yield beautiful values from orange to red to burgundy.
To create the deepest shade of red, use root at 100% WOF (weight of fiber), less to yield more coral/orange tones. Use with Calcium Carbonate as a color shifter to redden and deepen the shade.
Reuse your dye bath multiple times - each will yield lighter and lighter shades. Or, use the spent roots in eco-printing on fabrics or paper.
