Local:
Fuchsin is any of several red to purple dyes consisting of the salts (hydrochloride or acetate) of rosaniline and pararosaniline. The chemical structural body is triaminotriphenylmethane. It posses a brilliant green sheen crystals which produce red solution when dissolved. The solution is employed in coloring textiles and leather. It dyes animal and vegetable in nature. It is used as a bacterial stain. It is also used in the commercial preparation of other dyes.

Acid Fuchsin (acid magenta): a mixture of sulfonated fuchsins used in Andrade's indicator and in various complex stains.
Basic Fuchsin (basic magenta): yellow to green powder; soluble in water and alcohol; a mixture of fuchsins and magenta II; dark green powder; used for staining the tubercle bacillus, for distinguishing between coli and aerogenes bact, as an antifungal agent in Castellani's paint, as a germicide, and as a histologic stain, pH indicator.
Methyl Violet (crystal violet; gentian violet) : a derivative of pararosaniline; dark green powder; used as an antiallergen and bactericide, acid-base indicator and for the Gram stain; the Flemming triple stain with iodine; and Newton's crystal violet-iodine technique, and in dyeing textile.
