Just an FYI: the example Beáta provided is an excellent one for showing how to create your own color map.
You can also change a color map programmatically, if you don't want to create a new color map file.
See color_19.ncl at:
http://www.ncl.ucar.edu/Applications/color.shtml#ex19
This uses read_colormap_file to read in the desired color map ("amwg") and then sets the first color to white.
Cheers,

Hi Marston,
You can produce a new .rgb color palette by copy „amwg256.rgb” and rename it e.g „amwg2”. Open the created amwg2.rgb file and rewrite the first rgb numbers: 146 112 219 to 255 255 255 and save the file. After that, you have to set your environment variable based on http://www.ncl.ucar.edu/Document/Graphics/create_color_table.shtml to use awg2.rgb in your script.
I hope I could help you!
Best regards,
Beata

Hi,
I am using the color palette "amwg” which sets a light purple color for the lowest value range.
However, I would like to set this part of the spectrum to “white” instead.
I cannot find an example of how this can be done – if it can be done.
Does anyone have any idea? Appreciate your thoughts.
Best,
/M
