Van Gieson solution stains collagen in what color?

Explanation:
Van Gieson stain differentiates connective tissue by color, with collagen fibers highlighted in red/pink against a yellow background. This stain combines picric acid (yellow) and acid fuchsin (red); collagen has an affinity for the red dye, so the fibers appear red while surrounding tissue takes on the yellow hue. This contrast makes collagen stand out clearly, which is why red is the correct color. Other colors like blue, green, or purple belong to other staining systems and are not used to identify collagen with Van Gieson.
