Sometimes terrain is pitch black.
The only way I have found to reproduce this is:
1. Generating new terrain
2. Re-rendering new terrian
I have never seen this happen on horizontal surfaces, but it happens all the time on the sides of mountains. The only way to fix it is to destroy some blocks that are effected, and the rest in the area will sometimes fix themselves. Sometimes all I have to do is walk into the dark are and it will fix.
