Gram staining involves four steps. First cells are stained with crystal violet followed by the addition of a setting agent for the stain (iodine). Then alcohol is applied which selectively removes the stain from only the Gram negative cells. Finally a secondary stain safranin is added which counterstains the decolorized cells pink.
