交通信号灯为什么选择红黄绿三种色彩呢?
Why do traffic lights choose red, yellow, green, and three colors?
在道路交通中,中止仍是通行是与咱们生命安全休戚相关的。所以,用来表明这两种言语的色彩,既要简单被看到,还得不简单被看混。现在,咱们来看看,交通信号灯是不是契合这个规范。
In road traffic, stopping or passing is closely related to our life safety. Therefore, the color used to express the two languages is easy to be seen and not easy to be confused. Now let's see if the traffic lights are up to this standard.
首要,咱们来介绍一个关于色彩的小常识。人们常用一个标有各种色彩的圆环来对色彩进行摆放,在色彩环上间隔越远的色彩,色彩差异就越大,更简单被咱们所区别。赤色和绿色别离坐落色彩环的两头,这表明两者差异非常大,所以不简单弄混。
First, let's introduce a little knowledge about hue. People often use a ring with a variety of colors to arrange the color, the farther the color in the tone ring, the greater the difference in hue, and more easily distinguished by us. Red and green are located on both sides of the tonal loop, which means that the difference between them is very large, so it is not easy to mix up.
而黄色呢,是处于赤色和绿色中间的一种色彩,也就是说黄色与红绿色差异也很大。而且,赤色和黄色光的波长都很长,简单被人们的视觉观察到。所以呢,咱们看到的交通信号灯就是由这三种色彩所组成的。
And yellow is a kind of color between red and green, that is to say, yellow is different from red and green. Moreover, the wavelengths of red and yellow light are very long, which are easy to be observed by people's vision. So the traffic lights we see are made up of these three colors.
