Who's idea was it to make red represent stop and green to mean go?

Answer 1

The ideas, I presume, was conceived most naturally as red is the colour of blood, and therefore a possible sign of bloodshed, signifying danger; blood is something so vital to life that upon seeing it or its close resemblance anywhere outside its natural place, the human body, naturally becomes a sight of alarm. However, when red appears in, for example, roses that matters take and entirely different meaningfulness, and even then red signifies passion and possibilities of a passionate encounter - something we definitely do not like while we are our and about driving a precious cargo of ourselves.

Whereas green is the colour of ‘all clear’ in nature, a colour signifying growth and harmony. And I think it is due to the natural harmony of our biological system with the rest of the nature that we find green right at the centre of the spectrum of seven colours, with red at the one extreme.

Now the question that whose idea was it to make red represent stop and green to mean go, as I said before, could have been conceived most naturally, without much ado. It could have been somewhat like the idea of ‘inventing’ a wheel, the origin of which cannot be explored as it is so natural for thing to get rolling while in motion. There are many functions so natural to human mind that we hardly pay any attention to them when we bring them in our utilisation, startling, jumping or suddenly turning our head upon seeing or hearing something unusual, are some of the examples.

Answer 2

The visible light is divided into 7 distinct colours.

They are the colours of the rainbow, from Violet to Red.

Red light has the longest wavelength and hence can travel a longer distance than the rest without distorted. Followed by Orange, Yellow and Green. While Violet has the shortest wavelenght and gets distorted easily.

Since stopping a vehicle is more important, when there is a danger than letting it go, Red was chosen for Stop.

The nest signal was the colour Orange as it can travel second longest. So it was chosen for Caution.

The third would have been Yellow as it can travel the third longest, but it is not too easy to differentiate Yellow from Orange. So the next one in the line, Green was chosen for Go.

Answer 3

Red is usually the color of fire, chaos, etc denoting destruction, danger and harm. The color red also trigger/represent some negative emotions like anger and hatred. And thus STOP.

Green is usually the color of peace, as we can see from the trees, forests, grass, etc, which is also representing nature's balance. And thus GO.

Answer 4

red is danger that is why it is stop and I think green means go because they both start with G

Answer 5

good question, but the color red generally can speed up heart rate, and inspires a sense of warning or alarm and the color green is kind of sothing and makes me think of energy. that might have something to do with it.

Answer 6

red is danger and green is safe so danger ahead stop and green safer go.

Answer 7

I read somewhere , that if you cannot see colours , the 3 different shades are different to the un colour seeing eye

Answer 8

there's a scientific background to it,red can be visible from a loooooooooooooooong distance due to its scattering properties,etc,so used to signal stop
