Hi Liz,
Most of the colormaps available to NCL are ASCII files, and thus you
can edit them and create new colormaps (or just change the existing
ones.) The ones you can edit reside in the directory
$NCARG_ROOT/lib/ncarg/colormaps.
To add an extra white color to "BlWhRe":
1. Copy $NCARG_ROOT/lib/ncarg/colormaps/BlWhRe.rgb to
a new file in the same directory. Call it
something like "$NCARG_ROOT/lib/ncarg/colormaps/BlWhWhRe.rgb"
2. Edit this new file and find the white color you want to
duplicate. I believe the one you are interested in is on
line 53:
255 255 255
Make a duplicate copy of this line.
3. You now have a new colormap, called "BlWhWhRe" that
you can load from NCL.
