This problem is reasonably common for me, BTW. I can have a carbon monoxide
field with an average/background of 60 ppb, but variations from 30 to 550

Jody,
This has come up before and the consensus seemed to be that for the anomaly
data sets knowing where the zero is is very important and the default color
limits will probably get that wrong. So long as the user has to set the
limits, they can also select one of the diverging color maps.

Hi,
This is a great initiative, I love colormaps and am always disatisfied.
However, I am concerned about these proposed defaults. As Ben says, there are
two types of data sets: “intensity” or “density” data, and data sets with a
natural zero (i.e. positive or negative anomaly or velocity).

Furthermore, I think there is some work being done to add functionality to
the Norm to allow specifying a middle value along with a vmin and a vmax.
