The purpose, by the way, is to create black-free separations of images
that mostly use flat-ish somewhat-saturated colors (think comics).
I.e. I do not care so much about the potential resulting muddiness of
black and neutral areas; those would be afterwards manually replaced
with sensible proportions solid/rich black.
