physical features
Red has the lowest frequency in the visible light band of physics, which makes it have many unique properties different from other colors.
The lowest frequency of red means the longest wavelength, and the longest wavelength means the strongest diffraction ability and the strongest obstacle-crossing ability. Therefore, when the red light is used as the warning light, it can be observed effectively even in the bad visual conditions such as foggy days, which is also the fundamental reason why the red light is used as the stop sign.
Red light has the lowest light frequency and the longest light wave, which causes it to focus on the retina of the eye to form a larger image than other colors. Therefore, if you have two objects of the same size in front of you, the red object always looks bigger than the blue one, even if the brightness of red and blue are exactly the same. Because of this feature, red (and other warm colors) are also called "expanding colors" and "advancing colors", while blue (and other cool colors) are called "shrinking colors" and "retreating colors".
