    Purple colored cells and pink colored cells after the Gram stain (assuming the Gram stain was completed successfully) means that there are at least two species of bacteria in the sample and one species is Gram-positive and one species is Gram-negative.

    The species that is Gram-positive has a thick layer of peptidoglycan in its cell wall and does not have an outer membrane.

    The species that is Gram-negative has a thin layer of peptidoglycan in its cell wall and an outer membrane containing lipopolysaccharide (LPS).
