      <div class="">Anyways, I guess I am advocating trying to find a
        colormap with a very obvious central hue to represent zero.
         Anomaly data sets are *very* common, so having a default
        colormap that doesn’t do something reasonable with them may be a
        turn off to new users.  <br>

    I agree that jet does a bad job with anomaly data, but I disagree
    that having a diverging colormap as default (or even a "diverging"
    argument to anything that takes a cmap value) would solve that. Very
    often the "zero" of an anomaly is not at the center of the extrema,
    and requires creating a custom diverging colormap anyway (see
    attached example).<br>

    OT, I recently found a nice alternative to jet here:

    It takes care of my biggest crib with jet, which is that there is
    not enough perceptual variation in the middle of the range.<br>
