Their are two types of theories in the world one is based on science (scientists) and second is homescientist(our first teacher 'you got it right') they both have theories for everything in this world and their theories are always different from eachother
Let's discuss one of the theories:-
- why red colour is used for danger sign?
= As per science: 
The primary reason why the red color is used for danger signals is that red light is scattered(बिखरा) the least by air molecules. red which has the highest wavelength of all the colors we can see is scattered(बिखरा) the least. So red light is able to travel the longest distance through fog, rain, and the alike.
Second reason is that red is the one that was found to be most easily noticed by humans.
= As per homescientist:
Their are few examples i want to give you which my homescientist told me:
- example of ANT(🐜)- Have you ever noticed that black ant never bite you but red ant instantly bite you reason one why red is used for danger colour..
- example of pepper(🌶️)- to the the point red pepper is very spicy in comparison of black pepper that is the reason why red is used as a danger colour..
I am stunned after listening to these examples but what can i do i cannot argue with her because i want to life more ....
