Iron acts as both a modifier and mordant. Ferrous sulfate can be used to darken or sadden, shades for deep purple, varied grays, olive greens, and rust tones.  

Iron modifiers extend the range of colors produced and improve dye fastness. As a mordant, iron improves light and wash fastness.  

 We recommend using iron as a post-mordant with myrobalan to produce grey, black walnut for an improved formula, osage orange to extract olive, and madder paste for purple and rust tones.
