The pottery figurines unearthed from the pit of Qin Terracotta Warriors and Horses were originally colored, and most of the colors had fallen off when they were unearthed. Only mottled remnants are left on the terracotta figures, and some of the more colorful ones are still as new. Through the analysis of the color of pottery figurines, we can get a general understanding of the characteristics of various costume colors of Qin figurines, which provides a valuable example for studying the costume color and military uniform equipment in Qin Dynasty.

Through the preliminary statistics and analysis of the colors of the colorful clothes of the unearthed pottery figurines, it is known that there are many colors of the clothes of the Qin figurines, such as pink green, vermilion, bordeaux, pink, pink purple, sky blue, white and ochre. The collar, sleeves and lapels are also inlaid with colored edges. The color of trousers is generally pink green, and there are red, sky blue, pink purple, white and so on. In a word, the clothes of Qin Terracotta Warriors and Horses are colorful, but there is no uniform color. Among many colors, pink green, vermilion, pink purple and sky blue are the most commonly used, so these four colors should be the main colors of Qin figurines. Tests show that these colors are minerals.

Red is made of cinnabar, red lead and ochre. Green is malachite, blue is azurite, purple is the synthesis of lead and azurite, brown is limonite, white is lead white and kaolin, and black is amorphous carbon. These minerals are the main pigments in China's traditional paintings. The use of such rich mineral pigments in the Terracotta Warriors shows that the working people in China were able to produce and widely use these pigments more than 2,000 years ago. This is of great significance not only in the history of painting art, but also in the history of world science and technology.
