Colouration of microorganisms by applying single dye to a fixed smear is termed simple staining. One covers the fixed smear with stain for specific period after which this solution is washed off with water and slide blotted dry. The gram stain procedure distinguishes between gram positive and gram negative groups by coloring these cells red or violet. It was developed by danish microbiologist hans christian gram in 1884 as an effective method to distinguish between bacteria with different types of cell walls and even today it remains one of the most frequently used staining techniques. The microorganism is invisible to the naked eye therefore to make it visible the staining is performed which gives divergence to a microscopic image. Gram stain is a very important differential staining technique used in the initial characterization and classification of bacteria in microbiology.

Stains work by increasing the contrast between different cellular components thereby highlighting specific cell structures. In preparation for staining a small sample of microorganisms is placed on a slide and permitted to air dry. The primary stain crystal violet binds to peptidoglycan coloring cells purple. Both gram positive and gram negative cells have peptidoglycan in their cell walls so initially all bacteria stain violet.
