Instinctively the occurrence of red makes us wary, as we connect it with heat and the potential danger of burning. The effect of red on the eye is quite unusual. For the colour to be seen, the eye itself makes internal adjustments. This alteration means that we see red objects as closer than they really are. Being the colour of blood, red has symbolic links with living and life. Wearing red, eating red foods and surrounding yourself with red increases the body’s ability to absorb iron, the metal that is responsible for the colour of haemoglobin in the blood. If speed, danger, daring or courage is involved the red quality of the activity increases. When expressing red emotions, the heart beats faster, the capillaries dilate and the skin becomes flushed and feels warm. Red is thought of as an immediate colour. Red can result in very selfish behaviour, a focus on personal needs and survival above everything else. Red brings focus to the physicality of life, to the process of living. Without red we become listless and out of touch with reality and we fail to live our dreams in this world. Red can easily lead to excess as its own nature is impulsive and reckless. When a woman wears red, it has an immediacy and boldness. It is closely associated with sex appeal, and also with illicit passion.
