numerize color ranges

[Ninanoki]

I'd like to create an action to select some color range with tolerance, surround every such spot with a border and put a number inside all those shapes. So later after printing image on a painting paper I could paint on those spot with correct color. Is Photoshop best tool to do that or do you know any other?

1-image->mode->index color->16 (no dither, no transparency)

2-filter->stylize->find edges?
