Men are red and women are green

Brown University scientist Adrian Nestor found that men's faces are red and women's are green. His lab analyzed the faces of about 200 white men and women (of each sex) who were photographed without makeup under the same lighting conditions using a 3D scanner. Then, he used a program to analyze the red and green ratios of individual faces and found that some men's faces were red, while most women's faces were mostly green. The researchers' findings could be applied to showers or cat eye recognition
