A pale blue can look pretty much pink and a dark pink can resemble just about blue. Only an seasoned, educated lab tech should study and report Gram stains due to the a lot of artifacts seen on a slide. As soon as the shape and color from the bacteria has been determined, the bacteria can be classified. Unique classes of bacteria respond to distinct antibiotics.

This will tell the doctor specifically which antibiotic will kill the infection. Sensitivity tests are usually not completed on standard bacteria.
