Unsure... rescaling with bilinear interpolation happens before the palette
is applied, so it other
values that were not there in the original map, and then they get colored.

I did not translate the colormap back to human visible colors, but I'm
guessing green is on one end
of the colormap, and the blue is on the other end, right?

There is currently no way to apply the palette first, and then do the
rescaling (and eventual
reprojection) of image with interpolation. Doing that would allow the
interpolation to just blend between
green and blue, without going throught the other colors in the palette.
It could certainly be added, but it's not a quick change. If you can
develop in Java and know about image
processing I can point you to the location in the code where the processing
is done.
Or, if you are in a position to sponsor development, you can check out the
commercial support page and
inquire companies about implementing the change for you:
