In ancient times, the color grade of officials' clothing was divided into two types: primary colors and secondary colors. Among them, the primary colors include the five pure colors of cyan, red, yellow, white, and black, while the secondary colors are a mixture of the five colors of cyan, red-cyan, light red, light cyan, purple, and brown-yellow.
If you want to know what color clothes were worn by officials of rank three or above in ancient times, then the answer is D, purple.
The idea for obtaining this answer is that during the Northern and Southern Dynasties, my country established a five-level official uniform system, including five colors: vermilion, purple, scarlet (dark red), green, and cyan. In the Tang Dynasty, officials of the third rank and above wore purple official uniforms, officials of the fourth rank wore dark crimson, officials of the fifth rank wore light crimson, and so on.
I hope this answer can help you solve your problem. If you have other questions or need more help, please feel free to ask me questions.
