颜色对安全所起的作用是很大的,主要的有两方面,一方面是隐蔽性,即物体与背景的颜色和明亮度相接近时,彼此不容易被区分出来,例如:士兵穿上与战场相类似颜色的服装能保存自己的安全而减少伤亡。另一方面是暴露性,即物体与背景的色彩度相互显得很分明,明亮度也相差很大(即反差大)时,物体很容易从背景中被区分出来, The role of color in safety is great. There are two major aspects, one is concealment, that is, objects are not easily distinguished from each other when they are close to the color and brightness of the background. For example, soldiers wear Costumes with similar colors on the battlefield can save their own safety and reduce casualties. On the other hand is exposed, that is, the color of the object and the background are very distinct from each other, the brightness is also very different (that is, large contrast), the object can be easily distinguished from the background,
