Why did the people coose the red colour to represent dangers? if u find the answer, then why?

Answer 1

IT IS BECAUSE RED COLOR IS VISIBLE FROM FAR . OUR EYE CAN SEE RED COLOR FROM FAR DISTANCE. THAT IS WHY DANGER SINGS ARE MOST WRITTEN OVER RED COLOR

Answer 2

People react to red more than they do to, say, yellow, because of what they naturally associate it with (poisonous berries, as well as things like fire, and blood). yellow, on the other hand, is a more warm, welcoming colour.
Also, it stands out more, in fog and when it's getting dark and things. If it was green or something, it would get lost if it was around trees, or such, and your eyes just wouldn't see it. Same sort of reasons as why they use yellow on black to mark things underwater - it's the most visible thing in that environment.

Answer 3

Red has always been symbolic of blood.

However, in many Middle-eastern civilisations it was the symbolic representation of fire and associated with power and importance - a colour which stood out.

The bright red was also the colour of royality, and restricted to people of wealth. this is beacause the red dye produced by the madder root dye was not colourfast and these deep red clothes were worn by the lower classes. Marron could not to be confused with the brilliant colour crimson which was produced by using the expensive kermes and cochineal dyes producing cloth which could only be afforded only by the wealthy.

In Western cultures Red is thus the colour of fire and blood, so it is associated with energy, war, danger, strength, power, determination as well as passion, desire, and love. Is associated with sense of seriousness, readiness for a serious spiritual or political encounter. It is also associated with sacrificial rites and the shedding of blood in Pre colombian and Eastern traditions as well. Red is therefore used as a symbol of heightened spiritual and political mood, sacrifice and struggle.


Phychologically, Red is a very emotionally intense color. It actually enhances human metabolism, increases respiration rate, and raises blood pressure. The same effect happens to bulls, who will charge the colour.

For the symbolism of danger, you have to take into account, It has very high visibility, which is why stop signs, stoplights, and fire equipment are usually painted red.

They discovered this in time of old. A knight wearing red, would stand out like a 'sore thumb' and thus was asking for attention on the battlefeild. Thus in heraldry, red is used to indicate courage. It is a colour found in many national flags.

Red brings text and images to the foreground. Use it as an accent colour to stimulate people to make quick decisions; it is a perfect colour for 'Buy Now' or 'Click Here' buttons on Internet banners and websites.

In advertising, red is often used to evoke erotic feelings (red lips, red nails, red-light districts, 'Lady in Red', etc).

Red is widely used to indicate danger (high voltage signs, traffic lights). This colour is also commonly associated with energy, so you can use it when promoting energy drinks, games, cars, items related to sports and high physical activity.

The first danger sign created, was the Jolly Rodger, the pirate sign, which was a scarlet red flag. this was the Jolly Rouge in French, and was displayed to put fear in its victims during a slow sea chase under sail.

Answer 4

Signs are red because the colour red on the visible spectrum is at the top end therefore it reaches the eye first and makes you realise there is a danger or probelm.

Answer 5

red is a colour of attention. the best pollinated flowers are red. it is a colour of warning. the inner lining of the venus fly trap and other carnivorous plants is red. poisonous berries are usually red. warning colouration in most noxious species tends to be red or some variation on it. Blood is red. organisms in all nature, including human beings, have adapted to respond to red in two very general ways; avoidance and escape. as to why, red has the shortest wavelength in the visible portion of the electromagnetic spectrum. this means it has the most intensity; high ionising power because of its high frequency, and basically makes more of an impression.

Answer 6

Not only does red provide the greatest amount of contrast with most natural and manmade backgrounds (green/yellow grass and trees, brown or grey bricks), it is also the color that our eyes perceive the longest as light fades. The rods of the eye can pick up shades of red long after other colors have ceased to be perceived.

Answer 7

The same colour as blood. People associate blood with injury or danger.

Answer 8

red represents danger because it is the same colour as blood.

Answer 9

I was told it was red for the spilling of blood same as why the British used red for their uniforms so that it would not show the colour of blood.

Answer 10

I reckon it is because our blood is red - and if we bleed we are potentially in danger - hence the colour red signifies danger!

Answer 11

The choice of one color over another is totally arbitrary.Also, originally red signified hot because fire got red as in red hot. So keeping with what had already been established the rest was just fundamental.
