A lot of time is passed since the release of this project; meanwhile, I refined the colourmatch script, found some new alternatives, and I’m quite sure that, if I will do a new version, it will have a lot less artefacts than the old one - still not sure if I can avoid them all, though, but a workaround is always possible.

Mind that it will NOT be released immediately, but, as for the moment I have it not in my todo list, I could always add it, if someone could be interested in an eventual V2.0, of course.
