What solution of a dye or group of dyes that imparts a color to microorganisms?
A common solution used to impart color to microorganisms is the Gram stain, which uses a combination of crystal violet and safranin dyes. Crystal violet stains all bacteria purple initially, then iodine is used to fix the dye in the cell wall. Alcohol treatment differentially removes the dye from certain bacteria, allowing the counterstain safranin to color those bacteria pink or red.
