  Illustrator script to copy selected color values in the form [TYPE]=[VALUES] to a user's clipboard,
  preferring SPOT color names over values
  Discussion: https://community.adobe.com/t5/illustrator-discussions/copy-color-values-to-clipboard/m-p/13791617

  Modification by Sergey Osokin, https://github.com/creold:
  - Added path collection within groups
  - Added gradient and grayscale color support
  - Added flags to get Spot color values and Spot tint values
  - Color values are written to the clipboard in order of object coordinates
