Also this now should be on my source
So in Gmic Artistic/ Color Sketch

the filter create 2 duplicates of the image
on the first run Hard sKetch filter and this will give the sketch lines
the second duplicate is posterized (actually quantized that was the closest option available in gmic) and optionally blurred, and will add a colored BG to the sketch

I've been playing with this filter allready and gives great results.

David added today 2 new useful commands to gmic , -colormap and -autoindex that may be quite useful here

So may be soon a new version with more color options of this and the other "Recolored-BW filters i uploaded yesterday

In any case new version would have a slightly different name and command name to avoid conflicts
( all what possible before would remain possible as a subset, only more possibility would be added, and in this case will be possible without add too complexity to the controls )

PS i believe i forgot to post this
