Botanical Colors madder extract will produce pale pink and peach shades all the way through a deep, wine-colored red. Madder extract dyes to its deepest colors with an alum mordant and the addition of calcium carbonate. If you add a mild acid to your dyebath, such as cream of tartar, you will create a soft orange shade. 50g of madder extract will dye approximately 750g of fiber (1.65 pounds) to a dark red shade.
