Answer:

due to imperfections in the staining

Explanation:
if you skip the decolorization phase and therefore not resorb the violet stain from the wall of the gram-negative bacteria, which will not provide a base for the obtaining of safranin stain which should stain the gram-negative bacteria red or pinkish, the gram-negative bacteria will have the same color as the gram-positive, so all the cells will be purple
