What color were the military uniforms of various countries during the Spring and Autumn Period and the Warring States Period?

During the Spring and Autumn Period and the Warring States Period, because the ancient worship of gods still influenced that era, the theory of yin and yang divination still prevailed, which directly led to the fact that the dress colors and national colors of various countries were determined according to destiny. Therefore, during the Spring and Autumn Period and the Warring States Period, the colors of national uniforms were determined according to the virtues of each country, and the colors of the country should be consistent with the virtues of this country, so that the country can prosper.

Wei was separated from the State of Jin and was orthodox, and inherited the fire virtue of the Zhou Dynasty. Therefore, Wei also inherited the fire virtue of the State of Jin, with red costumes and red uniforms including flags. Ye Zhao is a native of Jin, and like Wei, the three clans are divided into Jin. Naturally, Zhao's military uniform is red, too? In fact, although Zhao was divorced from the State of Jin, it divined its unique costume culture and deduced the virtue of fire from divination, so the color of Zhao was blue with seven dividends and three points.

The development of costume color in Qi State is complicated. From the beginning, it inherited the fire virtue of the Zhou royal family, but in the later Tianqi era, the princes competed for hegemony, and Qi interpreted the fire virtue, and the colors of military uniforms and flags turned purple. Yan is a real royal aristocrat, but he thinks that the fire virtue inherited from the Zhou royal family will face the end of decline, so he deduces again and finally establishes his own water virtue, so the unified color of Qi is blue in the end.

In addition, Chu is also very special, especially Chu is from barbarians and has never had its own virtue, but it was not until the Warring States period that it followed the trend and deduced its own virtue, that is, Tude, so the color of Chu's military uniform was khaki. The Qin Dynasty came from the far west and never followed the Central Plains to establish its own virtue. The whole country is still black and has never changed, so its military uniform is black and full of mystery.
