auto
Paints isolated points in their selected colour but where multiple points in the same layer overlap it adjusts the clour by darkening it. This means that for isolated points (most or all points in a non-crowded plot, or outliers in a crowded plot) it behaves just like flat mode, but it's easy to see where overdense regions lie.
This is like density mode, but with no user-configurable options.
Usage:
shadingN=auto colorN=<rrggbb>|red|blue|...
