Warthin Starry Technique for Spirochetes results in spirochetes appearing as which color?

Explanation:
Warthin-Starry uses a silver impregnation method that deposits metallic silver onto the spirochetes, producing a very dark, almost black appearance against a pale background. This high-contrast staining makes the slender, spiral bacteria easy to see under light microscopy. The silver-based process, not a dye, is what gives the organisms their black color, so blue or brown wouldn’t be the result you’d expect with this technique.
