Hi Rick,
<div><br>
</div>
<div>Thanks for your help. I was mostly concerned about finding similarly sized color tables in the color table and using the cnFillPalette to call the tables, so that each plot would have a unique colorbar while still using the same plot res. </div>
<div><br>
</div>
<div>Cheers,</div>

<div>Hi Jonathan,</div>

</div>
<div>I don't fully understand what you are trying to do, and why you might need named colors. So taking a guess here, there is the read_colormap_file() that you can use to read one of the colormaps show in the gallery link, and from that you can directly
assign the result to cnFillPalette</div>

Hi NCL,<br>
<br>
The predefined colormaps are excellent examples of colors. <br>
However, from my experience, the gsn_define_colormap(wks, colors) limits the flexibility of NCL.<br>
<br>
Whereas, the res@cnFillPalette has flexibility. <br>
<br>
I am attempting to generate a multi paneled plot, and switching the res@cnFillPalette, but I still want to use the color maps.<br>
<br>
Is there a page that has “named colors” of the color maps? <br>
<a href="https://www.ncl.ucar.edu/Document/Graphics/named_colors.shtml" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Document/Graphics/named_colors.shtml</a><br>
This page has example colors, but I find it difficult to reproduce these colormaps:<br>
<a href="https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml</a><br>
<br>
<br>
Cheers,<br>
-Jonathan<br>
