A Day Without A Woman, which coincides with International Women’s Day, is a movement that seeks to show the vital role women play in both the domestic and global economy. It also aims to bring attention to the lower wages, sexual harassment, discrimination, and job insecurity that women often face. Those participating are encouraged to take off from paid or unpaid work, shop solely at small, women or minority-owned businesses, and wear red—which is the official color of the movement. That color was chosen because it “signifies love and sacrifice, and is the color of energy and action,” Tamika Mallory, a co-chair of the Women’s March on Washington, previously told Fortune.

Facebook has rolled out similar features in the past. In 2015, the social media giant released a rainbow-colored filter to celebrate gay pride. And, after the terrorist attacks in Paris in November 2016, users could put a blue, white, and red filter over their profile picture.
