Permanent Hairdye

Description
A collection of five hairdye bottles, fused together into an inseperable cluster from an unknown force. The bottles are red, green, blue, white, and black, meaning any color can be created through mixing. The bottles constantly refill themselves.

When applied to hair, the hair is instantly and permanently changed to that color. If applied to the scalp, any further hair will also grow in that color. The only way to undo this effect is to mix the original hair color and reapply it.

The exception is hair color that is magically recolored through mutations, which either temporarily works (like normal hair dye), or does not work at all (in the case of particularly weird hair, such as Mae's). Be careful, as it does stain skin and furniture and while those stains are not permanent, they are much harder to wash off than normal hair dye stains.

Trivia

 * While many love this artifact in theory, there's plenty of people too afraid to use it.
