Does violet beauregard stay blue forever?

In "Willy Wonka & the Chocolate Factory," Violet Beauregarde does indeed turn blue after chewing the experimental gum, but it's implied that she eventually returns to her normal color after the effects wear off. The film suggests that her transformation is not permanent, as she is taken to the juicing room to get the blueberry juice out of her system. In the end, her experience serves as a lesson about the consequences of greed and impatience.
