When it first appears, a bruise will be reddish looking, reflecting the color of the blood in the skin. By 1-2 days, the reddish iron from the blood undergoes a change and the bruise will appear blue or purple. By day 6, the color changes to green and by day 8-9, the bruise will appear yellowish-brown.

How long does bruising take to come out?

In most cases, your bruise will be gone — or almost invisible — in about two weeks. In response to being struck, your skin will typically look pink or red. Within one or two days of your injury, the blood that has collected at the injury site turns a bluish or dark purple color.
