Ovulation test: ovulating women wear red

Researchers Alec Beall and Jessica Tracy from the University of British Columbia enlisted 124 women to participate in a study in relation to women’s ovulation and the colour. Women were told to report the number of days since their last period and the colour of the shirt they wore on each day.

Women close to ovulation were more likely to wear a red/pink-coloured shirt compared to women at low-conception risk; 40 percent vs. 7 percent. They found that 76 percent of women in Sample A and 80 percent of women in Sample B who were wearing red/pink were at peak fertility, suggesting that red/pink-coloured clothing is a strong indicator of ovulation.
