Bruises are areas of skin discoloration and usually follow some injury to the skin or body tissue. Due to the injury, the vessels underlying the skin rupture, and blood extravasates into the tissues outside the blood vessels. The skin is usually intact, though there may be a small abrasion at the point of impact with a bruise that surrounds the abrasion.
Changing color is part and parcel of the bruising process. Initially, the bruises look red and angry looking, with some swelling. As time passes, bruises turn blue, black, green, and an intervening constellation of colors. The initial swelling is due to the blood and the fluid that the body secretes in response to any injury. The pigment in blood that gives its characteristic red color is hemoglobin. Hemoglobin in tissues undergoes chemical degradation, and the different colors you see are those of the byproducts of this degradation.
