Not because it’s Christmas! – We’re all annoyed by those “red eyes” that show up in photographs when we use a flash. But did you know that men’s FACES can turn out red too? (And WOMEN’S faces can look green!)

Why is this? Because male faces really do have a red tint, while female faces have a naturally green hue. We may have evolved this way to help us tell men from women at a distance.

In, Jeanna Bryner quotes researcher Michael Tarr as saying, “Just looking at the average color in faces you can reliably tell 70 or 80% of the time whether it’s a male or female face.

“The finding also has implications for facial recognition technology, advertising, as well as studies of how and why women apply make-up. So color could be another cue used by facial recognition systems or perhaps as another data point for cosmetics concoctors who could, say, make a foundation or rouge to enhance or cover up greener areas on a woman’s face.”
