In the Brown-Hopps Gram stain for tissues, Gram-positive organisms appear which color?

Explanation:
In the Brown-Hopps Gram stain for tissues, the thick-walled Gram-positive bacteria retain the crystal violet-iodine complex and take on a dark, intense color. This appears as blue-black under the stain, which is how Gram-positive organisms are visualized in this method. Gram-negative bacteria, on the other hand, are decolorized and then counterstained, ending up pink-red. So the best answer is the blue-black appearance for Gram-positive organisms in this staining technique.
