Different types of materials show up different colors under the gram stain process. For example, gram positive bacteria vs. gram negative bacteria show up differently (as colors) under the microscope using the gram stain vs. the simple stain. You get a blue or purple for a gram positive and a red for a gram negative.

gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.
