How many colors does the Red Army wear? There are yellow ones?

The uniforms of the Red Army are basically gray-blue, but the dyes used in different bases are different, which leads to different colors of uniforms. It seems that the first and second armies are light in color and the fourth army is dark in color. But there is no yellow one.

At the beginning of the Anti-Japanese War, the colors of the military uniforms of the Eighth Route Army and the New Fourth Army were basically similar to those of the Red Army. But later, due to economic difficulties, military uniforms came from capture, and clothing colors began to be diverse.

By the time of the war of liberation, the colors of PLA uniforms were not uniform and varied greatly. Generally speaking, the East China Field Army and the Northeast Field Army are basically yellow series, while the Northwest Field Army and the Central Plains Field Army are basically gray-blue.
