In Gomori's One-Step Trichrome Stain, what color do nuclei appear?

Explanation:
Nuclei appear black in this stain because the nuclear dye in Gomori's One-Step Trichrome produces a dark blue-black color, which contrasts with the red staining of muscle cytoplasm and the green staining of collagen. This color scheme—black nuclei, red muscle, green collagen—helps distinguish cellular outlines from connective tissue components in a single step.
