Since there are two sets of svg images of the Alfonso-X pieces, I downloaded both and compared them. The PyChess files were much larger, and they wouldn't display in Edge or load in Inkscape. The other images came in both black and white, but I needed only the white pieces. But these didn't have a fill color, which would have made recoloring them impossible. I fixed that by loading each one into Inkscape and adding a fill color in the appropriate places. Finally, I had to manually edit some to correct an error that had crept up in using Inkscape. Now that that's all done, I have a set of SVG images for the Alfonso-X set that work with Game Courier or the Diagram Designer and can be recolored. Thanks for the help.
