With release 9.0, the color architecture of Ghostscript was updated to primarily use the ICC\cite{ICC} format for its color management needs. Prior to this release, Ghostscript's color architecture was based heavily upon PostScript\cite{PS} Color Management (PCM). This is due to the fact that Ghostscript was designed prior to the ICC format and likely even before there was much thought about digital color management. At that point in time, color management was very much an art with someone adjusting controls to achieve the proper output color.
-Today, almost all print color management is performed using ICC profiles as opposed to PCM. This fact along with the desire to create a faster, more flexible design was the motivation for the color architectural changes in release 9.0. Since 9.0, several new features and capabilities have been added. As of the 9.21 release, features of the color architecture include:
