In the Fite method, the organisms stain which color?

Explanation:
In the Fite method, acid-fast organisms retain the red color because the primary stain, carbolfuchsin, is trapped in the waxy, mycolic-acid–rich cell walls of these bacteria. The decolorizer is milder than in other acid-fast methods, so the organisms resist decolorization while the background is counterstained to provide contrast. As a result, the organisms appear red against a blue/green background.
