What are bruises? Bruises are bluish or purple-coloured patches that appear on the skin when tiny blood vessels, called capillaries, break or burst underneath. The blood from the capillaries leaks into the soft tissue under your skin, causing the discolouration.
Healing / Color Change. Initially, a fresh bruise may actually be reddish. It will then turn blue or dark purple within a few hours, then yellow or green as it heals. It is the hemoglobin in the red blood cells and the breakdown products of the hemoglobin that cause the coloration seen in bruises as they age. contusion is a bump that happens under the skin after an injury. This bump is caused when fluid collects under the skin. A hematoma is also a bump that happens under the skin after an injury. But this bump is caused by blood that collects under the skin. Each can be called a bruise.
