How many colors are there in Tang Dynasty's clothing?

Every product, every product and every official dress in the Tang Dynasty is purple.

Four products and five products are scarlet, and six products and seven products are green. The eight official uniforms are dark blue. The official uniform is light blue. The color of official uniforms is a sign to distinguish the size and status of officials, so the color of official uniforms can't be worn casually. The so-called purple gift means that the official's grade is not enough to wear purple, but the emperor allows him to wear purple.

The origin of the color system of official uniforms in Tang Dynasty

The Tang Dynasty called itself "Tude" and advocated yellow, but this yellow is not the lemon yellow and banana yellow we see in our daily life, but the yellow with red in it. Tang Gaozu asked the monarch and his subjects to have obvious differences in clothing, because at that time, both the monarch and his subjects could wear yellow and purple, which easily confused their identities.

Confucius was one of the most outstanding thinkers and educators in the Spring and Autumn Period and the Warring States Period. The Confucianism he founded had a far-reaching influence on the history of our country. In order to adapt to the social hierarchy at that time, Confucius emphasized that people's food, clothing, housing and transportation should conform to the "ritual" norms. In addition to covering up the basic functions of the body, clothes should also be able to "know the price of their clothes in the world", not only in materials, styles, but also in colors.
