In Southgate's mucicarmine technique, epithelial acid mucins stain which color?

Explanation:
Acid mucins in the epithelium are colored red. In the mucicarmine technique, the Carmine-alum pigment binds specifically to the sulfated and carboxylated mucins, giving them a deep red/red-rose color, while a blue counterstain (often hematoxylin) colors the nuclei for contrast. This makes red the characteristic color for epithelial acid mucins in this stain.
