The primary reason why the colour 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 colour. Therefore blue which has the least wavelength of all the visibleradiations is scattered the most and red which has the highest wavelength of all the colours we can see is scattered the least.
