What are the colors of official uniforms for Tang Dynasty officials?

In the Tang Dynasty, the first-, second-, and third-grade official uniforms were purple.

The fourth and fifth grade official uniforms were scarlet the sixth and seventh grade official uniforms were green. The eighth-grade official uniform is dark green. Ninth-grade official uniforms are light green. The color of the official uniform is to distinguish between the size of the official grade, the status of the sign of the high and low, so the color of the official's dress can not be worn casually. The so-called granting of purple means that the official's rank is not yet high enough to wear purple, but is authorized by the emperor to wear purple.

The origin of the Tang Dynasty official color system

The Tang Dynasty, which was known as "Tudor", revered the color yellow, but this yellow is not the lemon yellow, banana yellow that we see in our daily lives, but a little bit of red with reddish yellow. The Tang emperor demanded a clear distinction in dress, because at the time, both kings and ministers were allowed to wear yellow and purple, which could easily confuse them.

Confucius was one of the most outstanding thinkers and educators during the Spring and Autumn and Warring States Periods, and the Confucianism he founded had a profound impact on the history of China. In order to adapt to the social hierarchy at that time, Confucius emphasized that people's clothing, food, housing and behavior should be in line with the norms of "etiquette", clothes, in addition to the basic function of covering the body, but also to be able to "the world to see their clothes to know the nobility and inferiority", not only in terms of materials, styles, and even the color of the differentiation. The color of the clothes is not only in the material and style, but also in the color of the clothes.
