In Masson's Trichrome staining, what color is elastin?

Explanation:
Masson's Trichrome uses a dye combination that colors collagen blue and muscle/cytoplasm red. Elastin fibers tend to take on the red hue in this protocol, due to the way the counterstains interact with elastin, so they appear red against the blue collagen background. That’s why red is the expected color for elastin in this stain.
