Sorry, fashionistas. When it comes to what color to wear to be sexier and more desirable to men, it’s red — not black — that does the trick.

New research published in the Journal of Personality and Social Psychology shows that the color red, relative to other achromatic and chromatic colors, enhances male’s attraction to females in nonhumans and humans alike.

Men may not even realize that red turns them on more than, say, blue, green or brown, and a woman in red may not necessarily be perceived as more likeable, kind or intelligent in the hue. But she’s definitely got more power in the va-va-va-voom department.

"The findings have clear practical implications for men and women in the mating game and, perhaps, for fashion consultants, product designers and marketers,” the journal states. “Furthermore, the findings document the value of extending research on signal coloration to humans and of considering color as something of a common language, both within and across species.”

Men also were more likely to say they wanted to have sex with a woman and that they would be willing to spend more on a date if she were in red.

"We think that red, due to the association with hearts and Valentine’s Day and lingerie and things like that, takes on a sexy meaning," Andrew Elliot, Ph.D., a professor of psychology at the University of Rochester in New York, told CNN. "There’s also a possibility — a rather provocative possibility — that there’s a deeply embedded sort of tendency for heterosexual men to see red as an attraction cue because that’s what happens in the wild."
