I'm not an engineer (wish I was tho) and I didn't sleep at a Holiday Inn, so my ignorant guess (in euber layman's terminology) is the dark color is from heat as well as a collapse or degradation of the molecular structure of the metal (tearing it self apart and compacting on its self) as it fractures?
The brighter outer area is a faster fracture and experienced less compressed energy when fracturing?
pretty lame right?
