Is crystal violet the same as gentian violet?

Are crystal violet and gentian violet the same thing?

Yes. “Crystal violet” and “gentian violet” refer to the same dye, commonly known as violet (a triphenylmethane dye used in staining and disinfectant contexts). The names are used interchangeably in practice.

Why do they have different names if they’re the same dye?

They come from different naming conventions:
- “Crystal violet” is a common chemical/product name tied to how the dye appears and is sold.
- “Gentian violet” comes from the traditional association with the dye’s use and/or color naming (including historical references to “gentian” as the shade family).

Are there any “gotchas” people should watch for?

In some settings, products may list different additives, different concentrations, or different salt forms (for example, solutions vs. stains). Those differences affect strength and how the dye is used, even though the core dye name refers to the same violet compound.

If you share the label or exact concentration (e.g., “1% solution” or “0.5%”), I can help interpret whether the product you have matches what you mean by crystal/gentian violet.
