I'm not sure what I'm looking at in that picture exactly, or how to
distinguish a good result from a poor one -- could you elaborate?

FYI I should also note that we're planning on additionally providing
isoluminant (or approximately isoluminant) variants for whatever colormaps
we end up contributing, exactly for cases where you want to preserve the
lightness channel for shading effects. So in any case you'll have a choice
between "mapA" and "mapA-isoluminant", etc.
