Crystal violet or Gentian violet (also known as Methyl Violet 10B, hexamethyl pararosaniline chloride, or pyoctanin(e)) is a triarylmethane dye. The dye is used as a histological stain and in Gram’s method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic properties and was formerly important as a topical antiseptic. The medical use of the dye has been largely superseded by more modern drugs, although it is still listed by the World Health Organization.
The name "gentian violet" was originally used for a mixture of methyl pararosaniline dyes (methyl violet) but is now often considered a synonym for crystal violet. The name refers to its colour, being like that of the petals of a gentian flower; it is not made from gentians or from violets.

Famous quotes containing the words crystal and/or violet:
“Wise men read very sharply all your private history in your look and gait and behavior. The whole economy of nature is bent on expression. The tell-tale body is all tongues. Men are like Geneva watches with crystal faces which expose the whole movement.”
—Ralph Waldo Emerson (1803–1882)
“I know a bank where the wild thyme blows,
Where oxlips and the nodding violet grows,
Quite overcanopied with luscious woodbine,
With sweet musk-roses, and with eglantine:
There sleeps Titania sometime of the night,
Lulled in these flowers with dances and delight.”
—William Shakespeare (1564–1616)
