Hi,

I'm not totally sure what your question is -- are you trying to extend the
colors in the colormap, or plot two different channels of data?  In any
case, you might take a look at the examples on RGBa color at:

http://ncl.ucar.edu/Applications/rgbacolor.shtml

Examples 7, 10, and 13 in particular use multiple colormaps.

Hope that helps...
Rick
