Purple and violet have been royal colors since 1200 BCE because of the Phoenicians, as they discovered the Tyrian purple–a very prized hue. This dye was expensive and difficult to get, so it became a rare luxury and a symbol of wealth.
Violet is important from a materialistic point of view, but it also has a very spiritual meaning too. It is the color of the third-eye chakra, so it stands for wisdom. Violet is also about intuition, magic, healing, and the unknown. It is even associated with the tarot, specifically with the card of the Moon. This major arcana card indicates that something is hidden and that fears should be considered.
Now, when we think about Samhain colors, blue violet takes on a unique role. Samhain, a Celtic festival marking the end of the harvest season and the beginning of winter, is often associated with colors like orange, black, and deep red. However, blue violet's mystical qualities make it a fitting addition to the Samhain color palette, enhancing the spiritual and magical aspects of this ancient celebration. As you can see, the typical eerie mood of Halloween is very well created using blue violet: it’s a magical color, connected with the cosmos, Samhain, cartomancy, and fortune-telling in general.
