Re: errors when using rgb color map

If I understand your question correctly, I think you simply need to set the special resurce "gsnSpreadColorEnd" to the last value in the color map that you want to be part of your contour colors.

The default of this resource is -1, which is the last color in your colormap. You added gray to the end of your colormap, and that's why you are seeing it in your contour colors.
Try setting opts_r@gsnSpreadColorEnd = -2 (second to the last color in your color map). You may also want to set opts_r@gsnSpreadColors to True to span the full color map.
