1. In a color rendering system, a method for dynamically limiting total colorant coverage, the method comprising: defining a first volume of a multi-dimensional colorant cube to comprise any colorant combination that exceeds a total coverage limit; defining a second volume of the multi-dimensional cube to comprise any colorant combination that is within the total coverage limit; identifying a reference point within the second volume to define a third volume of the multi-dimensional cube, wherein the entirety of the third volume is within the second volume; defining a foreshort region consisting of the union of the first volume and the third volume; and using resultant colors in a color rendering process performed by the color rendering system for all input colors falling within the foreshort region comprising bijectively transforming the input colors into the resultant colors, the resultant colors all lying within the third volume.
