Is a colour management system useful for colour specification?
Not yet. But colour management system interfaces in the future are likely to include the ability to accommodate commercial proprietary colour specification systems such as PANTONE[tm] and COLORCURVE[tm]. These vendors are likely to provide their colour specification systems in shrink-wrapped form to plug into colour managers. In this way, users will have guaranteed colour accuracy among applications and peripherals, and application vendors will no longer need to pay to license these systems individually.
