Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in Biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes. Stains may be used to define and examine bulk tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells, for instance), or organelles within individual cells.
In biochemistry it involves adding a class-specific (DNA, proteins, lipids, carbohydrates) dye to a substrate to qualify or quantify the presence of a specific compound. Staining and fluorescent tagging can serve similar purposes. Biological staining is also used to mark cells in flow cytometry, and to flag proteins or nucleic acids in gel electrophoresis.
Staining is not limited to biological materials, it can also be used to study the morphology of other materials for example the lamellar structures of semi-crystalline polymers or the domain structures of block copolymers.
Methylene blue
A simple stain has a positive charge.
A simple stain reagent is a type of stain, such as crystal violet or methylene blue, that is used to colorize cells or tissues for microscopic examination. These stains bind to cells and provide contrast to make them visible under a microscope. Simple stains are a quick and easy method to visualize the basic morphology and structure of cells.
Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
The result of simple staining of microorganisms is that they can be identified and studied under a microscope.

It's simple, because it's a stain.
Carbolfuchsin can be used as a simple stain by staining bacterial cells pink to differentiate them from the background. The pH of the carbolfuchsin stain is typically around 6.0, but may vary depending on the specific formulation of the stain.
A simple stain like iodine can make cell parts show up that would otherwise be nearly invisible since they are colorless.A simple stain like iodine will reveal a cell's morphology.
simple answer is NO

One advantage of a simple stain over a wet mount is that a simple stain allows for better visualization of cellular structures and morphology as the staining process enhances contrast. This can be especially useful when trying to identify specific characteristics or structures within the sample.
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.

The major advantage of the gram stain over the simple stain is that it differentiates bacteria into two main groups based on cell wall composition (Gram-positive and Gram-negative). This provides important information about bacterial characteristics and helps in determining appropriate treatment strategies.
