For me and many designers, color is an asset with information associated with it that I need to follow this asset as it moves from different design programs. With metadata attached to file, I would be able to utilize the features in InDesign and other programs to auto populate this information into text fields. Additionally if this metadata ASE file was a library shared between many users and the any of the tagged information on a color was changed, this update would shoot out to any documents using this color. It would reduce:
-errors by relying on one source of truth for all the color information.
-time spent typing in this information and free up time for design instead of administrative tasks.
-time spent tracking down where colors were used to update any changes.
