New description:

 It would be desirable to assert certain must-have colors in advance.
         E.g. "`preset=#F00 #010203`" alike.
         .
         Which should not exceed "[https://ffmpeg.org/ffmpeg-
 filters.html#palettegen max_colors]".
         And the ordering in generated palette should be readapted.
         (according to frequency of occurrence (descending), presumably?)
