Here are some possibilities for what you might be looking for:
* "Inter-violet": This could be a made-up word referring to something that exists between two shades of violet.
* "Ultraviolet": This is a real word referring to electromagnetic radiation with a wavelength shorter than visible light, but longer than X-rays.
* "Violet": This refers to a color, typically a purplish-blue hue.
If you can provide more context, I might be able to help you figure out what you meant.
