What color do reticulin fibers appear in Gordon and Sweets Stain for Reticular Fibers?

Explanation:
Reticular fibers are argentaffin (argyrophilic), so they pick up silver in special silver-impregnation stains. In Gordon and Sweets, the silver deposits on the delicate reticular network, turning those fibers black while the surrounding tissue is counterstained lighter. This high-contrast black appearance helps visualize the fine reticular framework, which is especially important in tissues like liver, spleen, and lymph nodes. Other colors (red, blue, yellow) come from different staining chemistries, not this silver-based method, so they wouldn’t appear black with Gordon and Sweets.
