I have a load of reciepts with black text on white paper. Red and blue pens have been used over the image. Is it possible to basically nuke the red and blue, while keeping the black text and white background? I've tried Kill Color keeper, and it doesn't do what I need. Thanks

I recently got a pebble watch, and came across this amazing plugin when trying to make a custom watchface. I needed to dither an image, and this seemed to almost be able to do it. I edited the plugin with the Pebble Time palette, and figured it would be worth posting here. I've included the edited source, the icon, the palette text file I made, and the compiled plugin.
