Mordants are classified into two categories: a) Basic mordant: React with acidic dyes e.g. alum, ferrous sulfate, cetylpyridinium chloride etc. b) Acidic mordant : React with basic dyes e.g. picric acid, tannic acid etc. [2] Direct Staining: Carried out without mordant. Indirect Staining: Staining with the aid of a mordant.

Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria.
If the bacteria is acid-fast the bacteria will retain the initial red color of the dye because they are able to resist the destaining by acid alcohol (0.4–1% HCl in 70% EtOH). [4] Additionally, it can be used for the staining of bacterial spores. Carbol-fuchsin is also used as a topical antiseptic and antifungal. [citation needed]
