Very nice description of a classic imaging problem. Luckily, this is precisely what the color to alpha plug-in was designed to handle. Filters | Color | Color To Alpha, select your purple color, let it run, and wholah· The major drawback is that it doesn't only operate on "border" pixels - it operates on every single pixel in the image (or current selection). This means: 1) If you have a real life background like from a photo, you probably don't have a solid color to remove 2) If your foreground has any component of the color you're trying to remove, that will be removed too. #2 is worked around by repainting "under" the image with the same color you just removed. For #1... you can keep selecting colors that don't get hit and re-running it, but my suggestion is to get it close and do the rest of the touchup by hand.
