That requires a vertex_index map, either passed into the algorithm or 
within your graph.

No, not unless your graph uses vecS as the vertex container.

Looking at this, it appears the problem is that BGL's trying to use a 
nonexistent vertex_index map to create the color map and then failing 
because error_property_not_found (what is returned if you try to use a 
property that doesn't exist) is not a valid index map.
