Red vs. Blue

Unity Engine

Why do some prefab instances appears red in color in the Hierarchy?

As I understand it, blue means it’s a normal prefab instance and black means the instance link has been broken by a change to a non-parameterized property of the instance. But what’s the deal with red?

The red shows that the prefab has been deleted from the project folder.
