give scientific reason

Danger signals are red colour.

$\huge \underline \bold \red{ANSWER}$

The primary reason why the color red is used for danger signals is that red light is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color.

Answer 2

danger signals are red in colour because a red colour is scattered by the least by air water or dust molecules the effect of scattering is inversely related to the fourth power of the wavelength of a given colour since the colour red has the highest wavelength of all the colours it gets scatter the least
