The color, RED, not only grabs attention, but it also triggers sexual associations. At an unconscious level the color red signals sexual interest and arousal.
Building off this idea, researchers examined whether women unconsciously choose to wear red-colored outfits when it makes the most sense to attract sexual attention – when they are ovulating.
What the researchers found is that women are 3.5 times more likely to wear a red-colored shirt during their most fertile time of the month.
Research shows that ovulation is not silent. Women send multiple indicators, including a change of voice, appearance, and clothing, in an attempt to signal their reproductive status.
