Violet, the most exotic color, has long represented royalty. Back in the middle ages, because of how it was acquired and made, the color crimson was made from the mucous glands of snails. It took a thousand snails to yield 1 gram of crimson; making it was very expensive, and only royalty could afford it. Therefore, subliminally it can represent wealth, both monetarily and spiritually (Figure 6). It is the color of the twilight sky, exotic bird plumage, and butterflies. In spiritual terms, it represents transition, as evidenced by the religious Lent and Advent colorings. It is a deep, mysterious hue. It is mystical and meditative.
