Methyl Violet 2B is a staining, transparent violet dye. It turns yellow when exposed to strong acids.
Methyl Violet 2B will fade with exposure to ultraviolet light.
Methyl Violet 2B is harmful to living cells and organisms, so it is diluted in medical and biological applications as a topical fungicide or disinfectant. Methyl Violet 2B may cause irritation to the skin, eyes, respiratory tract, or gastrointestinal tract, however no long-term or chronic ill effects are known.
Methyl Violet dyes are used in medical, biological, and pharmaceutical applications. Common Methyl Violets include Methyl Violet 2B, Methyl Violet 6B, and Methyl Violet 10B. They are often used as biological stains for cytology. The common name Gentian Violet is sometimes applied to this class of dyes. In very dilute form, Gentian Violet is often used as an antifungal agent, including in applications where there is contact with skin and other tissue. Paper impregnanted with Methyl Violet 2B is used to test pH because it turns yellow at pH 0.

Rhodamine B is a staining violet dye that has flourescent properties. It is extremely soluble in both water and alcohol. In art materials, it is laked as a pigment.
Rhodamine B, like all fluorescent dyes, is not considered to be lightfast. It is recommended for permanent works of art only if they can be adequately protected from exposure to ultraviolet light.
The fluorescent dye Rhodamine B is toxic, and its use is banned in food, textiles, and cosmetics. It is harmful if swallowed, inhaled, or absorbed through the skin. It has been shown to be carcinogenic in rats when injected subcutaneously, producing local sarcomas. However, when it is laked as a pigment it can be biologically inactive and hence non-toxic. With proper preparation, the pigment Rhodamine B Lake is considered harmless, even if ingested.
Rhodamine B, discovered in 1887, is used as a staining fluorescent dye in the biological sciences, for microscopy. It is also used as a laser dye. Because of its low cost, high tinting strength, solubility in water and alcohol, and relative stability for a fluorescent, it has sometimes been used as a food colorant, even though its use in food and cosmetics has been banned in most countries for many years. There have been several highly publicized recalls of food and cosmetic products contaminated with Rhodamine B.
