What does the purple crystal in tarot stand for?

Purple is rarely used in Vitaro cards, and usually symbolizes luxury, wealth or kingship (purple grapes on gold coin clothes). In fact, the devil's card in Vitaro has purple. Pay attention. It's on the tail of a woman chained up. This is the same as the grape string on the clothes of the king of gold coins, which means that if you indulge in material desires, the shackles of material will bind you to see the devil (in the devil's card, a man's tail is a flame, symbolizing his impulse to get himself into trouble)

Purple is usually combined with spiritual energy and mysterious things, such as the purple curtain in Justice. In other modern tarot cards, we can see that purple is widely used.
