Claim One:
1. A computer implemented method of creating a color look-up-table for use by an imaging system which uses a resource to display an image and provides an attribute of the image, the method comprising: a) selecting a threshold value of resource usage and metric of the attribute by the imaging system; b) accessing a predetermined color look-up-table representing a mapping of color values of a first color gamut to color values displayable by the imaging system, the predetermined color look-up-table having nodes defining colors to be displayed for the color values; c) comparing the resource usage and attribute values associated with the nodes to the threshold value and thereby determining a first set of nodes of the predetermined look-up-table having a resource usage and attribute value less than the threshold value and a second set of nodes having the resource usage and attribute value not less than the threshold value; and d) creating a further look-up-table which maps the said color values of the first color gamut to the first set of nodes, by removing the second set of nodes and generating, using the first set of nodes, a replacement second set of nodes that have the resource usage and attribute values less than the threshold value.
