Red is most often associated with intense emotions. It can represent love, passion, and desire as well as danger, anger, and aggression. Additionally, red is a symbol of good fortune and prosperity in many Asian cultures.
Stop signs are red because the color is associated with caution and danger, so it is more likely to capture the attention of drivers. Additionally, red has a long wavelength, making it easily visible from far distances.
To appreciate the color red, walk as far away as you can from the stop sign and notice how much the color stands out compared to artifacts of other colors. Can you still read the sign or does its connotation precede it?
