In microscopy and microbiology, dyes used for staining generally consist of two key components: a solvent and a chromogen. The solvent acts as a medium in which the dye is dissolved, allowing it to be applied evenly onto the specimen. The chromogen is the colored component of the dye, which contains the chromophore – the portion responsible for the dye's color. The chromogen interacts with cellular structures, enhancing their visibility under a microscope by imparting color to those structures.

This combination allows for effective staining of microorganisms and cells, facilitating the observation of their morphology and other characteristics. By understanding the role of both the solvent and the chromogen, students can better appreciate how different staining techniques work and how to choose appropriate stains for their specific applications in microbiological studies.
