The database is 8 gigabytes so it will take a minute to upload, but I put one of the output images on imgur:
The source color is in the top left corner and below it are colors darker than it ordered by lightness descending from top left to bottom right. The hue of all the colors is supposed to be similar but there is so much variance in the hue that really only 20% of these colors are usable.
This image would be printed out and if one of the colors is more accurate after printing, then the source color in the original art would be replaced with that other more accurate color.
