Gram stain, urethral exudate, from male with urethritis, 1974. Note the lack of gram negative intracellular diplococci. Gram-stain technique, which employs crystal violet as the primary stain, imparts a purplish-brown color to bacteria that stain Gram-positive. Those that stain with the pink-red fuchsin counterstain are said to stain Gram-negative. Image courtesy CDC/Dr. Norman Jacobs.
