Cocci, which are spherical bacteria, can appear in various colors depending on the staining method used. For example, when subjected to the Gram stain, Gram-positive cocci typically appear purple due to the thick peptidoglycan layer in their cell walls, while Gram-negative cocci appear pink. In other contexts, such as with specific dyes or under a microscope, their color can vary. Overall, the color of cocci is not fixed and depends on the conditions and methods used for observation.
