At those locations are aerodynamic slots in the wing that keep the wing tips from stalling before the rest of the wing.
As to the dark (black) coloring, I don't know, but it seems possible that the slots are protected from icing with pneumatic boots just like the leading edges of the wings and tail.

I wonder if it's just a different color paint where the slots are located?

Mike,
Looking at the two photos you posted above, I am more convinced it is de-icing boots. The top picture shows a wing with no de-icers and the bottom picture shows a wing with de-icers.
