Thousands are taking part in the social media #BlueforSudan campaign to show solidarity with protesters in Sudan.
The blue wave has spread across Twitter and Instagram via the hashtag as users attempt to honour one of the victims, Mohamed Mattar, whose favourite colour was reportedly blue.
A friend of Mattar’s who is also an Instagram beauty influencer said once he was murdered his friends and family changed their profile pictures to match his and now the colour represents all of the Sudanese people who have fallen in the uprising.
