[ncl-talk] RGB triplets colormap --> Two different figures, same script.

I think, the reason is that *for gsn_define_colormap*, you need to add both
background and foreground colours in the list when explicitly defining
colours triplets. So, in your list of color triplets, the second entry
should be "(/0.,0.,0./)".
Replace the colors variable in your script with following:
colors = (/"(/1.00, 1.00, 1.00/)","(/0.,0.,0./)", "(/0.98, 0.99, 1.00/)",
\
"(/0.98, 0.99, 1.00/)", "(/0.96, 0.98, 0.99/)", \
"(/0.95, 0.98, 0.99/)", "(/0.94, 0.98, 0.99/)", \
"(/0.93, 0.97, 0.99/)", "(/0.92, 0.97, 0.99/)", \
"(/0.91, 0.96, 0.99/)", "(/0.90, 0.96, 0.99/)", \
"(/0.89, 0.96, 0.99/)", "(/0.88, 0.95, 0.99/)", \
"(/0.87, 0.95, 0.98/)", "(/0.86, 0.94, 0.98/)", \
"(/0.85, 0.94, 0.98/)", "(/0.84, 0.94, 0.98/)", \
