You can import colors and gradients from other documents, adding either all or some of the swatches to the Swatches panel. You can load swatches from InDesign files (.indd), InDesign templates (.indt), Illustrator files (.ai or .eps), and Adobe Swatch Exchange files (.ase) created by InDesign, Illustrator, or Photoshop. Adobe Swatch Exchange files contain swatches saved in the Adobe Swatch Exchange format.
InDesign also includes color libraries from other color systems, such as the PANTONE Process Color System®.
