To see how to use several of the color functions, trying running the following example:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"

begin
  wks = gsn_open_wks("x11","color")

  gsn_define_colormap(wks,"BlueRed")
  gsn_draw_colormap(wks)              ; Draw the color map.
  gsn_reverse_colormap(wks)           ; Reverse the color map.
  gsn_draw_colormap(wks)              ; Draw the new color map.
end
