On Rainbow plates, typical colonies are black/gray. Positive test result: The indole reagent change colour to cerise red. So it looks like a little pink rod under the microscope. Also, E. Coli is a catalase positive bacteria, and that means it produces an enzyme called catalase. This can be tested by adding a few drops of hydrogen peroxide to a colony of bacteria, and catalase makes hydrogen peroxide dissociate into water and oxygen, making the mixture foam.
