ALWAYS mix light auburn with a brown color because light auburn by itself on gray hair may look violet. Light auburn by itself on brown hair will be a reddish brown or lighter auburn, depending on how much natural red tone you haver in your hair and how much your hair lightens. To make Ecocolors less permanent dilute the entire color mixture by half with water. ALWAYS do an allergy patch test and a strand test before applying any new color to your entire head.
