A recent study has shown that the color red increases people's attraction but the effect may not be limited to humans.
The research has shown that female monkeys also respond to the color red, suggesting that biology, rather than the culture, have been playing a fundamental role in the "red" reactions. And it could be possible that the color red and romance was a fundamental thing rooted in human biology.
Researchers said that female rhesus monkeys' interest in images of the opposite sex appeared to be influenced by extraneous color that suggested that the "red effect" was not unique to humans. Instead, the researchers have argued, it appeared to be supported by an "evolved biological mechanism."
Benjamin Y. Hayden, professor in brain and cognitive sciences at the University of Rochester, has explained that previous research has shown that the color red in a mating context made people more attractive, and in the fighting context made people seem more threatening and angry.
The researchers found that a significant female bias towards the images of male hindquarters, only when a red frame surrounded the image and they said that this was the first demonstration of an extraneous color effect in non-human primates.
In a second trial, the researchers had found that male monkeys had not shown a preference for the female hindquarters, even when surrounded by the color red.
The study appeared in the journal Evolution and Human Behavior.
