I tried searching the forum for a thread on this subject but didn't find one. The only text dealing with this issue I've found so far has been this:
Taken from the FAQ found on the Inkscape wiki.Inkscape uses the same file format for palettes as the GNU Image Manipulation Program (GIMP Colour Palettes, .gpl). To install a palette, copy the .gpl file to the share/palettes directory in your Inkscape installation.
Thanks in advance for any answers.
