An excellent cartographic trick is to use a halo color of the nearly same color as the background color (accumulated color of map.background + layers) where the labels are placed, but of a slightly darker or lighter hue.

The implementation of an algorithm to approach a best guess at this color when the label placement background does not vary significantly could result in some nice halos.
