Quote:.Is this tinting of the white spots a bug, or feature, LOL? Can it be circumvented, some way other than selecting color and inverting, for that majority of images that have more than 2 colors?
Nothing to do with Gimp. It is the poor base image you are using.
Bucket Fill with 'Fill similar colours'
1. Depends on where you click in the image and
2. The threshold value.
Reduce the threshold gets a better white but risks not including all of the mottled grey. See my earlier screenshot.
Learn to be flexible, not all procedures are suitable for all images. Use the Select -> Invert -> Fill procedure.
