In May-Grunwald Giemsa staining, what color do bacteria typically appear?

Explanation:
May-Grunwald Giemsa staining uses basic dyes that preferentially color acidic structures blue. Bacteria have nucleic acids and other components that bind these basic dyes strongly, so they appear blue (often blue-purple) under the microscope. This blue contrast helps them stand out against the pinkish cytoplasm of host cells stained by the eosin portion. While shade can vary with staining quality, the typical appearance of bacteria with this stain is blue.
