Red

A stimulant, red is the hottest of the warm colors. It's a strong color that conjures up a range of seemingly conflicting emotions from passionate love to violence and warfare. Studies show that red can have a physical effect, increasing the rate of respiration and raising blood pressure. The expression seeing red indicates anger and may stem not only from the stimulus of the color but from the natural flush (redness) of the cheeks, a physical reaction to anger, increased blood pressure, or physical exertion.

For your wardrobe, Use the color red to grab attention and to get people to take action. Use red when you don't want to sink into the background. Use red to suggest speed combined with confidence and perhaps even a dash of danger. A little bit of red goes a long way. Small doses can often be more effective than large amounts of this strong color. Multiple shades of red and even pink or orange can combine for a cheerful palette.
