Which staining protocol uses Neutral Red as a counterstain?

In silver-staining methods, a counterstain provides contrast so the darkly stained target structures stand out. Gordon and Sweet's silver stain uses Neutral Red as the counterstain, giving the background a pinkish color while the silver-impregnated structures (like reticular fibers or basement membranes) appear black. This combination makes those fine structural details easy to visualize under the microscope. Other staining protocols are designed for different targets and use different counterstains, so Neutral Red isn’t typically part of them.
