Differential Staining is a staining process which uses more than one chemical stain. Using multiple stains can better differentiate between different microorganisms or structures/cellular components of a single organism.
Differential staining is used to detect abnormalities in the proportion of different white blood cells in the blood. The process or results are called a WBC differential. This test is useful because many diseases alter the proportion of certain white blood cells. By analyzing these differences in combination with a clinical exam and other lab tests, medical professionals can diagnose disease.
One commonly recognizable use of differential staining is the Gram stain. Gram staining uses two dyes: Crystal violet and Fuchsin or Safranin (the counterstain) to differentiate between Gram-positivebacteria (large Peptidoglycan layer on outer surface of cell) and Gram-negative bacteria.

Staining technique in Cell biology | Simple and differential staining | Video 19
Cell staining is a technique used for the main purpose of increasing contrast through changing the color of some of the parts of the structure being observed thus allowing for a clearer view.
There are a variety of microscopic stains that can be used in microscopy. First of all, staining can be in-vivo or in-vitro. The difference between these is that whereas In-vivo staining refers to the staining of a biological matter while it is still alive, in-vitro staining refers to a staining technique where the biological matter is non-living.

Gram staining procedure animation - Principle, Procedure, Interpretation

--------------
Staining is an auxiliary technique used in microscopic techniques used to enhance the clarity of the microscopic image. Stains and dyes are widely used in the scientific field to highlight the structure of biological specimens, cells, tissues etc.
The most widely used staining procedure in microbiology is the Gram stain, discovered by the Danish scientist and physician Hans Christian Joachim Gram in 1884. Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives. The procedure is based on the ability of microorganisms to retain color of the stains used during the gram stain reaction. Gram-negative bacteria are decolorized by the alcohol, losing the color of the primary stain, purple. Gram-positive bacteria are not decolorized by alcohol and will remain as purple. After decolorization step, a counterstain is used to impart a pink color to the decolorized gram-negative organisms.
Importance of a Gram Stain:
---------------------------------------------
The Gram stain is a very important preliminary step in the initial characterization and classification of bacteria. It is also a key procedure in the identification of bacteria based on staining characteristics, enabling the bacteria to be examined using a light microscope. The bacteria present in an unstained smear are invisible when viewed using a light microscope. Once stained, the morphology and arrangement of the bacteria may be observed as well. Furthermore, it is also an important step in the screening of infectious agents in clinical specimens such as direct smears from a patient.
The Gram stain procedure enables bacteria to retain color of the stains, based on the differences in the chemical and physical properties of the cell wall.
1. Gram positive bacteria: Stain dark purple due to retaining the primary dye called Crystal Violet in the cell wall. Example: Staphylococcus aureus
2. Gram negative bacteria: Stain red or pink due to retaining the counter staining dye called Safranin.
Example: Escherichia coli

There are a variety of microscopic stains that can be used in microscopy. First of all, staining can be in-vivo or in-vitro. The difference between these is that whereas In-vivo staining refers to the staining of a biological matter while it is still alive, in-vitro staining refers to a staining technique where the biological matter is non-living.
There are two types of staining techniques Simple stains use only one type of stain to color whatever microorganism you are looking at. The problem is that these stains color the entire organism one color, making it difficult to tell the different parts apart. Differential stains use two or more different types of stains to show the different parts of the microorganism.
An example of this is the Gram stain, which uses three different dyes, Gram’s iodine, safranin, and crystal violet in sequence with an alcohol rinse between stages.
