In contrast, differential staining distinguishes organisms based on their interactions with multiple stains.

It was created for the brand: The Amazing Live Sea-Monkeys, by ad agency: Gertrude. On the other hand, the negatively charged chromophores in acidic dyes are repelled by negatively charged cell walls, making them negative stains. Thus, commonly used basic dyes such as basic fuchsin, crystal violet, malachite green, methylene blue, and safranin typically serve as positive stains.

megaterium appear to be white because they have not absorbed the negative red stain applied to the slide.
