A bruise will initially appear red, reflecting the color of the blood in the skin. But in a day or two, the site appears as a familiar black-and-blue mark. By about day six, the color changes to green and by day eight or nine, the bruise will appear yellowish-brown. Generally, a bruise is repaired by the body and the skin returns to normal in two to three weeks. Foot bruising can occur at any spot on the foot, from the toenail to the back of the heel, and often produces pain or discomfort in the area where it occurs (forefoot / toes, arch or heel).
