Question

Why are street signs green? and not another color?

Answer 1

Why are lane stripes white????Nice when it snows? Who was the rocket scientist who came up with that??

Answer 2

The first crude traffic light was a manually operated gas lantern installed in London around 1868. The signal consisted of two colors -- red meant "stop," while green meant "caution." One day the lantern exploded and injured the policeman who was operating it. It was painfully obvious a more efficient traffic signal was needed.

In 1920 Police Officer William Potts addressed the chaotic traffic of Detroit, Michigan, by co-opting the red, amber, and green automatic traffic light system used on railroads. Around the same time, the prolific African American inventor Garrett Morgan devised and patented the precursor to the automatic traffic lights we use today.

Apparently the colors of red and green were standard in the electrical industry at the time. The makers of railroad signals and traffic lights simply adopted the familiar color scheme.

We can really only speculate as to why these colors were originally used in the industry. An About.com entry on color symbolism points out that different colors evoke different emotions in humans. Red generally symbolizes danger or warning, making it a good choice for "stop." Green is calming to us, probably because it is prolific in nature and a sign of health and abundance, so it might have lent itself to mean "go."

Answer 3

There is a national color coding system for signs in the US as set up by the US DOT. Green signs are informational highway signs in regard to routes, streets, towns, cities, Etc. Blue signs denote rest areas,services, service plazas , parking areas and other safe to pull off for a break type places. Brown signs denote Public access to parks, lakes and other places of interest. Yellow signs denote road hazards and red signs denote places where required to stop, yeild or not do something.

Answer 4

i think thats a state by state basis, tho most of the national ones are green b/c the colorblindness and b/c cartographically speaking, any other color would be confusing.

blue usually represents water bodies on maps,

brown/black/green are roads,

white/yellow/brown are for land features,

red is for marking the scale and/or important places like hospitals, fire/police stations, etc.

orange is rare, but sometimes used for the actual city dots

green can be used for cemeteries, parks and wooded areas, tho for signs it just makes sense, for the reasons listed above.

Answer 5

As in residential street signs?

I've seen:  blue with white letters,  dark blue w/ white, white w/ black, brown w/ white and yellow w/ black  -- just to name a few combinations.   When cities are close to each other,  a dramatic change in street sign color schemes makes it easier to see where one city ends and another begins.
