What's so particular about the color of military uniforms?

Military strategists at all times and all over the world have always been very particular about the choice of military uniform color, because it is closely related to the arms of the army and the geographical and climatic environment, especially to estimate the special effect of military uniform color on people's vision and illusion. The color of military uniforms in different countries is determined by their own times, climate, geographical environment and traditional habits. The colors of ancient military uniforms were originally used to distinguish the enemy and the enemy on the battlefield. During the Middle Ages in Western Europe, there appeared a private army belonging to the nobility-earth cavalry. They bring their own clothes and have no uniforms. In combat, it is often difficult to distinguish between the enemy and ourselves, which is not conducive to combat. It was not until the end of 15 that mercenaries appeared in western Europe and stipulated the colors and styles of their military uniforms. During the period of Louis XIV, it was formally stipulated to use special styles of clothes as uniform. Guards wear white uniforms, dragoons wear red uniforms, and infantry wear gray uniforms.

In the long-term war practice, the ancient army of China gradually realized the importance of military uniform color, and generally emphasized the use of dark military uniforms. For example, in the Song Dynasty, it was put forward that "the ancients were all dressed in uniform and all were red." In other words, all officers and men in the army wear crimson clothes. The original intention of "uniform from top to bottom" is: First, military discipline can be serious and military capacity can be uniform; Second, it is conducive to identifying the enemy and ourselves in the war; Third, you can protect your commander on the battlefield and not become the "target" of the enemy. As for the soldiers wearing red, the advantage is that the color of the military uniform is exactly the same as the black and red wheels and war drums painted with livestock blood. In this way, even if someone is injured and bleeding in the battle, it is not easy to be seen by others, thus avoiding the fear of soldiers; Of course, the color of military uniforms in different dynasties is not necessarily the same, and even a dynasty does not necessarily use the same color. But no matter how the color changes, it is generally dark.

The lessons of war make people realize the special role of military uniform color in the army, especially in some special environments. Monochrome olive green protective clothing was widely used in World War I. This color is close to the color of grass and soil, and it is easy to hide yourself in battle. In the Second World War, camouflage clothing composed of multi-color deformed color blocks reappeared, which was suitable for camouflage of many Shan Ye grasslands. At that time, more than a dozen countries, such as Europe and America, had sent expeditionary forces in many parts of the world. In actual combat, camouflage uniforms consisting of six colors replaced monochrome olive-green military uniforms. Since then, they have mixed some special chemicals in six colors of dyes, which can make the infrared light reflected by these colors roughly similar to the reflection ability of the surrounding natural scenery, and make the color of military uniforms closer to the color environment of nature, thus confusing the enemy's sight. This special camouflage military uniform has been widely used in modern field troops.
