It’s common knowledge that red is a sign for passion and action-the color red has been used for hundreds of years in 
matador’s capes, Valentine’s cards, and even in traffic lights to grab attention.
Though scientists agree that red is a bold color that works to stimulate the optical nerve-it hasn’t been fully known why, until now.
Adam Pazda, a psychologist in the University of Rochester in New York, has conducted a study that might provide the answer as to why red works better than almost any other color in the spectrum to stimulate a response.
It likely has to do with biology. When primates’ estrogen levels peak, blood rushes to the skin and face to let males know that females are fertile. It was a trickle-down theory of basic reproductive responses for years, and now further research has verified the phenomenon.
Pazda conducted an experiment in which 25 males were shown two pictures-one of a woman wearing a more neutral color, and another of the same woman wearing red. The men were asked to gage, on a scale of 1 to 9, how receptive the women were to a sexual encounter.
On average, the men scored the woman in red’s disposition towards sex 1 to 1.5 points higher when she was wearing red, than when she was wearing a white shirt, or other mundane color.
What does this mean for society?
It means that a lady doesn’t necessarily have to be wearing a red dress in order to grab attention from the opposite sex-a red shirt, a red scarf, even a red purse can send a signal out to others that she is receptive to flirtation.
Christian Louboutin must have known what he was doing when he designed the famous heels that show a red bottom.It also makes more sense as to why cosmetic companies use red in their lipstick and blush products, and why the tones go over well with the general public.
The next time you want to get noticed, just remember to incorporate a little red into your outfit-it’s a scientific fact that you will stand out in a crowd!
