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
