That PDF did the trick! I was able to load it into Inkscape and convert it back to SVG and do some of the color filling that I had wanted to do.
Your comment before was also leading me down a good path before. Inkscape wasn’t inverting the colors because there was only one color! I was starting to play around with trying to get a shape that had both Black and White fill so that I could then make a negative copy of it. But you sent the PDF and that worked better. THANKS!
