Eric,
This is a very interesting question to me because ; How do we know what color these west rocks were prior to entering our Atmosphere?Maybe we don't? As seen in the video of the fall it looks to me that something came apart in mid-air. But maybe those are represented by only the broken ones found on the ground. What if the complete stones actually came in black? It is not a stretch to imagine that because we simply do not know the answer. There is no way we could know. Before you think I'm crazy consider the only bit of information we know for a fact was done by the Europeans called "stone6".

In this experiment none of the rocks turned black. Some of the rocks in fact did not change colors at all. and the ones that did, changed to a creamy white crust.
So, who is to say these rocks are not already black while traveling through space. The evidence here actually leans in that direction. Maybe these rocks were already coated with black crust and that is what protects them from evaporation when they travel through our atmosphere.
Again, this may sound silly but if you look at the evidence from this study and you acknowledge the fact that the things we do see in space are in fact already dark it does make you wonder. Maybe our atmosphere is not the reason they are black after all? Something else comes to mind, We have all seen pictures of meteors traveling through our atmosphere and then back out again. Wouldn't those accumulate crust and then continue on there journey? ???.
