Hi all,

Has anyone out there made any plots where the colorbar/colormap is part
grayscale, part color? For example, what I'd like to do for one application
is make some plots with a color palette like "NCV_bright," for instance,
where temperatures below 0ºC (say) get plotted in a grayscaled version of
the color palette, but grid cells with values above 0ºC get plotted with
the regular full-color palette. How would I go about doing that? Would I
have to manually replace the sub-zero part of my color palette with various
named gray colors? Thanks for any tips or ideas!
