How do we get the width and height of any color in Illustrator in a document. With PHOTOSHOP we know this when we select it in the Ctrl+ Color Palette in the channel, but how can we find it with ILLUSTRATOR. Can a script do this?

    Colors don't inherently have a width or a height. Do you mean Object? Illustrator has a Document Info Panel.

Ok better approach. Works only for CMYK documents for obvious reasons. Also since illustrator is based on objects wont do anything for raster/gradient/mesh elements

  1. Copy your arwork to safety!
  2. Do Edit → Color -> Adjust Color Balance
    • set Magenta, Yellow and black to -100
  3. Do a merge
  4. Delete white
  5. Select everything and read values form the transform panel

Can be recorded into a keyboard shortcut with the actions panel:
