The mordant reacts with the dye used in staining, to create a colored precipitate. It is the precipitate, not the dye itself, that can be observed after the excess dye is washed away.

As in the Gram stain? Iodine is used as a mordant to bind the stain into the cell wall, so as not to be washed out during the alcohol wash.
