Hemosiderin stained with Perl's Prussian Blue appears which color?

Explanation:
Perls' Prussian blue stain detects ferric iron (Fe3+) by forming an insoluble blue ferric ferrocyanide complex. Hemosiderin contains ferric iron, so these iron deposits appear as blue granules when stained, typically with a pink counterstain in the background. Therefore, the color seen with Perls' Prussian blue on hemosiderin is blue.
