first fact
For fashion lovers in general and purple color lovers in particular:
In the Middle Ages, the only ones who could wear purple were members of the nobility.
So the one whose color is purple is his favorite, and the one who believes in reincarnation, maybe in the previous incarnation you were members of the nobility, or you just have expensive taste...
Bonus fact: the fabrics that testified to a high aristocracy were among others velvet (which returned to our days like a storm wind even in the warmer seasons) and silk, which to this day is attributed to high status and durability.
