13. A non-transitory computer readable medium tangibly embodying programmed instructions which, when executed by a computer system, are operable for performing a method of color conversion on a presentation device, the method comprising: receiving a presentation datastream including presentation data and a first descriptor value identifying an input color space of the presentation data; processing the datastream to identify the first descriptor value; identifying a second descriptor value for an output color space of the presentation device; identifying a link color conversion Color Management Resource (CMR) using the first descriptor value from the presentation datastream and the second descriptor value, wherein the link color conversion CMR includes the first descriptor value, the second descriptor value, and a rule for converting the input color space to the output color space; and transmitting the link color conversion CMR and the presentation datastream to the presentation device for use by the presentation device to convert the presentation data for output at the presentation device.
