The colour red is one of the most striking hues to the human eye, capable of conveying a wide range of emotions. Its powerful, warm tone is often associated with passion, love and energy. However, it is also often used in warning signs because of its visual attention-grabbing role. Psychology has shown that red can increase heart rate and stimulate adrenaline production, making it the colour of action and excitement.
Its cultural meanings can vary: in the Western world it is the colour of romance and love, while in other cultures it is the colour of happiness and prosperity. In China, for example, red is a symbol of good luck and celebration. In marketing, it is often used to attract attention and stimulate certain impulses, as it can reinforce a sense of urgency or encourage a purchase. Its ability to dominate space and direct attention makes it a universally effective tool for visual communication.
