Which bruising color typically corresponds to 5–7 days after injury?

Explanation:
Bruise color progression reflects the breakdown of blood pigments during healing. Right after injury, a bruise is red from fresh blood. Over the next couple of days it often appears blue or purple as hemoglobin becomes deoxygenated. By about five to seven days, biliverdin forms, giving a greenish tint as the bruise progresses. Later, roughly seven to ten days and beyond, bilirubin appears, creating a yellow color as healing continues. So a green bruise around days 5–7 fits the expected biochemical timeline of pigment changes during recovery.
