[ncl-talk] replace part of colormap

[Beáta Szabó-Takács]

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
