As it turns out, showing a preference for the color red is a behavior exhibited in males throughout the animal kingdom, specifically primates. Homo sapiens, at least according to the findings in this landmark study, were simply following suit, being the animals that they are. (Looks like that charming “you and me baby ain’t nothing but mammals” song that your parents didn’t want you to listen to in middle school was onto something.) This attraction to the color red appears to be linked to the female cycle, according to the journal Personality and Social Psychology. Researchers observed that female monkeys actually reddened while ovulating and their mates responded to that change.
