In Mayer mucicarmine staining, what color is the background?

Explanation:
In Mayer mucicarmine staining, the key idea is that mucin is stained a bright pink to magenta, while the rest of the tissue takes on the color of the counterstain. The counterstain colors the background, producing a blue-toned background in the standard protocol. Some laboratories or specific protocol variants can yield a yellow background due to different counterstains or staining conditions, but blue is the typical background color you should expect.
