Differential staining uses more than one type of stain

Colors

It stains a microbial cell only one color

It stains a microbial cell two or more different colors

Significance

It helps to observe and identify the shape, size, structure, and arrangement of bacterial cells

It helps to differentiate between distinct types of bacterial species

Example

Methylene blue staining

Gram’s staining, acid fast staining
