Yes, it's that simple. A bit of crimson has the
power to put men in a lusty state of mind—one study even found they were
56 percent more likely to ask out a woman in a red top versus a white
one. That's because men are hardwired to respond to the hue: The color
was used as early as 10,000 B.C. in lip color and blush to mimic the red
flush we get when we're turned on. Throw on a red dress and let primal
instincts take over.
