Until the end of the Han Dynasty ca. 220 AD, the violet color, which was developed in a period 1000 BC, was used to be worn by the nobility and imperial family in Ancient China, because it symbolized high status and wealth. The color also symbolizes nobilty and spirituality, too. This is also common in Western culture.
We truely can imagine the nobleman, Gui Zu, walking through decorative Chinese gardens, wearing violet silk clothes.
