You have made a smear of a bacterial culture and have performed the Gram stain on it. Looking at the organism under the microscope, you notice that the cells do not seem to be the dark blue-purple of a gram-positive reaction, but instead are light blue. Your staining procedure was performed correctly. What is your best explanation as to why the bacteria have stained this way?

The way the dark blue is smeared is thin so it goes light when spread out
