Recolor Artwork keys colours by identity (model and exact values), so CMYK
colours stay CMYK and lookalikes stay apart. recolor.reduce groups the
selection's colours into rows (k-means in Lab, weighted by use; tints of a
global swatch share its row) with Preserve White/Black/Grays and Limit to
Library; recolor.apply maps rows by Exact, Preserve Tints, Scale Tints, Tints
and Shades or Hue Shift; recolor.randomize shuffles or varies new colours.
The dialog has Assign (rows with merge, separate, exclude, randomize, method,
library) and Edit (hue/saturation wheel with linked or unlinked handles,
brightness, harmony rules) tabs, and Edit Colors gains Recolor with Preset
(1/2/3 Color Job, Color Library). Colour parameters accept colour keys.
