ELi5: Why are some scars purple, some white, some brown, some red, and some pink?


Pretty much what the title says. Why does scar tissue come in so many colours?

In: Biology

Mostly due to age of the scar. As time goes by the scar heals more and becomes less inflamed, and color changes as a result. Severity of the injury also matters, and if you develop an abnormal scar like a keloid that will also cause discoloration.
