Reminder: in matplotlib, color mapping is done with the combination of a 
colormap and a norm.  This allows one to design a norm to handle the 
mapping, including any nonlinearity or difference between the handling 
of positive and negative values.  This is more general than customizing 
a colormap; once you have a norm to suit your purpose, you can use it 
with any colormap.

Maybe this is actually what you are already doing, but I wanted to point 
it out here in case some readers are not familiar with this 
colormap+norm strategy.</pre>

    Actually, I didn't use norms because I never quite figured out how
    to use them or how to make my own. If there's a way to create a norm
    with a custom mid-point, I'd love to know/use that.<br>
