In the Tang Dynasty, Buddhism, Taoism, Saman and aristocratic courts all popularized purple. The official uniforms of officials with three or more products were limited to purple, and purple robes were given to eminent monks to show their brilliance and influence. Japan also regards purple as a symbol of dignity.

In the third year of Dahua in Japan (AD 647), the "crown of seven colors and thirteen steps" was formulated. The highest color is purple, which is forbidden. You must have a corresponding official position to wear purple clothes. In heian period, only male members of the royal family (the emperor's father, the prince, etc. ) you can wear it. No one else is allowed to use it. Until the edo period, deep purple was a color that princes, warriors and civilians could not use at will.

After the ban on light purple was slightly lifted in Heian period, it was called ゆるし color (allowed color), and it was free to wear purple in Meiji period. In Meiji 18 (1885), Cuixi Girls' School, an aristocratic school, began to use purple as a school uniform, and Japan began to use purple clothes with confidence.

Today, under the long-term psychological influence, the use of purple in Japan is still somewhat taboo. If purple has a sad component, it is the influence of later literary works, because in Japan, purple has always symbolized nobility, and ordinary people wear purple clothes, which feels very unsuitable.
