The Blue for Sudan movement emerged in June 2019 following a violent crackdown on pro-democracy protesters in Khartoum. The specific shade of blue was the favorite color of Mohamed Mattar, a 26-year-old victim of the massacre who was killed while attempting to protect others. After his death, his family and friends changed their profile pictures to this blue in his honor, and the gesture quickly went viral globally. The meme serves as a powerful symbol of solidarity and a digital protest, used to bypass media blackouts and draw international attention to the humanitarian and political crisis in Sudan.
