In analyzing their data, the researchers found a clear connection between color and numbers of shares—they report that images heavy with reds, purples and pinks tended to garner a lot of shares (repins), whereas those saturated with black, yellow or blue, were less likely to see a lot of sharing.
– When it comes to Pinterest, colors matter. Researchers analyzed about 1 million posts on the site and found that images heavy on red, pink, or purple were repinned the most, reports Phys.org. By contrast, those with black, yellow, green, or blue fared the worst, according to the study in PloS One. Because the vast majority of Pinterest users are women, Biz Report suggests that advertisers should pay close attention to the results. Next up might be studies of other sharing sites such as Instagram and Flickr to see if the same holds true.
