This is how the test happens
In the Gram stain method, the violet dye is applied to the spots of bacteria and then it is washed with an organic solvent iodine solution. Thick cell bacteria remain of purple color and are called gram-positive. At the same time, bacteria with weak and thin cells are washed away and the purple spots disappear, they are called gram-negative.
