Green Bruises: A green bruise indicates that the site of injury has entered its concluding stages of healing. The bruise may transition from purple to green at the edges or center of the injury site. The dark-green color is due to the presence of a hemoglobin breakdown product called biliverdin. The last role of the word, "verdin," comes from the Latin word for "green."

Yellow Bruises: The final step of healing involves the bruise turning a yellow color. This is from the final breakdown product of hemoglobin appearing in your skin; it'due south known as bilirubin. Every bit your trunk clears the remaining cellular and other debris from the bruised area, the yellow paint fades and your skin returns to its original tone.
