When I said "'by config' sounds funny", I meant "'from config' may
be more natural". Perhaps name this read_graph_colors_config(), as
that (i.e. reading "log.graphColors") is what it does.

The correctness of the first loop relies on the fact that colors is
non-null when colors_max is not zero, and then the freeing of the
colors relies on something else. It is not wrong per-se, but it
will reduce the "Huh?" factor if you wrote it like so:
if (colors) {
/*
* Reinitialize, but keep the colors[] array.
* Note that the last entry is allocated for
* reset but colors_max does not count it, hence
* "i <= colors_max", not "i < colors_max".
*/
int i;
for (i = 0; i <= colors_max; i++)
free(colors[i]);
colors_max = 0;
}
