.ACB File Extension

Color books are used for creating images that conform to certain color standards. For example, some color catalogs are better for screen displays while others are better for scanning or print. In Photoshop CS5, you can choose a color book when selecting the Color Libraries button from the Color Picker window. Several ACB files are provided with the Photoshop installation within the \​Presets\​Color Books\​ directory.

Photoshop provides color books for color catalogs such as ANPA, DIC, FOCOLTONE, HKS, PANTONE, TOYO, and TRUMATCH.

NOTE: Adobe InDesign and Illustrator also use color books stored in ACB files.

To open a .acb file, you need compatible software that supports this file format.
