Is ringworm on black people red?

The answer is: yes

Ringworm is a common fungal infection of the skin that can affect people of all skin colors. On black people, ringworm may appear as red, brown, or even white patches on the skin. The patches are often round or oval in shape and may have a raised, scaly border. Ringworm can be itchy and uncomfortable, but it is usually not a serious infection. It can be treated with over-the-counter antifungal medications or with prescription medications if the infection is severe.
