It was the differences between systems ”different displays, different viewing conditions, and different software applications ”that created the need for color management.
Scientists went to work on the problem in the late 1980s, developing a model for color management that would eventually provide software tools to ensure that color would match, location-to-location and device-to-device. The first practical color management system, Apple ColorSync, arrived in 1991 and has undergone several significant improvements since. Over the years, Apple s ColorSync technology became the
