<div class="">Oh, BTW: read_colormap_file() will always return an array of Nx4, ie., RGB-alpha tuples. If you have previously set cnFillPalette with a named color map that consisted of only RGB tuples, then you might get an mis-match error if you try and

<div class="">Hi Rick,
<div class=""><br class="">
</div>
<div class="">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 class="">Hi Jonathan,</div>

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