This Is Why Traffic Lights Are Red, Yellow, and Green
Ever wondered why blue doesn’t mean go and brown mean stop?1..
The idea that red means stop and green means go has impacted our lives in more ways than just traffic signals. We have been taught from a young age that the color red means danger.2.. But why were those particular colors chosen for traffic lights in the first place? For something we have to look at every day, why couldn’t they have been prettier colors like magenta(紫红) and turquoise (天蓝色)?
It’s important to know that before there were traffic lights for cars, there were traffic signals for trains. At first, railroad companies used red to mean stop, white to mean go, and green to mean caution. As you could imagine, train conductors ran into a few problems with the color white meaning go— 3., with train conductors thinking they were all clear when they really weren’t. Railway companies eventually moved to the color green meaning go, and it’s been that way ever since.
As far as red goes, that’s always been a color that indicated danger, long before cars were even around. Red is the color with the longest wavelength. 4.. The color yellow was used to caution drivers because it has a slightly shorter wavelength than red, but not as short as green.
5.. Employ these driving rules first and know that traffic lights have certainly come a long way.
A. And the color green means it’s OK to move forward
B. Turns out, there’s a perfectly good explanation for it
C. It can be seen from a greater distance than other colors
D. bright white could easily be seen from a distance by us
E. bright white could easily be mistaken for stars at night
F. Why don’t we use blue to mean go and brown mean stop
G. So don’t get mad next time you’re impatiently waiting at a traffic light
