In Gomori Aldehyde Fuchsin staining, what color is elastin?

Explanation:
Elastin shows up as purple with Gomori aldehyde fuchsin staining. The aldehyde fuchsin component specifically binds to the elastic fibers, giving them a distinct purple (often mauve) color that stands out against the counterstained background. This contrast helps differentiate elastic tissue from collagen and other matrix components, which take on different colors with the same staining system. So, the purple hue is the hallmark of elastin in this stain.
