Why is the red, green and yellow colors chosen to control the traffic? Ever wondered, why don't it means to go with blue? Or why not it called to stop with the brown light? The orange color could also be used to stop it. But why?
In addition to traffic signals, red light means 'not to go' or 'stop' and Green means 'going' and these two color has a great influence in our lives. We know from the very beginning that red color means danger. even the Blood color is red. Again the color of the fire is also red. That's why red means danger. And green means 'all right you can go'. But why are these colors selected for traffic lights? Why is not a nice color like Blue and Magenta used?
To find the answer to this question, you need to know, the traffic lights used to be used for rail movement and control before the car. The rail was first used in the control of the** red** to stop, White is to be used for going and Green to be warned.
But train operators often got confused by white light. As the white light meant, all right you can go. So at night, they thought the bright star from the distance was empty, the road was empty. It is easy to go. In order to avoid the collision of railways and to avoid accidents, the railway authorities have finally started to use good lighting. From that to the traffic signals, green light has been used to mean to go.
Many years ago, the danger was indicated by the red. Red is meant that the danger is in front. Even before the car was available, the red light was meant to be danger. The reason for choosing the red light to denote the danger is its wavelength. Due to the length of the wavelength, red light can be seen from many distances in comparison to other lighting.
And the use of yellow light began to be alerted. Because its wavelength is slightly shorter than red, but not compared to green.
But you do believe or not, once the cars were turned off with yellow light. That's why you should go back to 1900. Then in some areas the mark of stopping was yellow. Because red light in some areas with weak light could not be seen very much. Eventually the material grew quite well over time, the power of reflection increased in many ways and at one point the sign of the block of red light was born. The arrival of the Red Stop sign happened.
Since yellow light is very clear at any time of the day, so the school zone, some traffic marks and the color of the school bus is yellow.
