1. In a color rendering system, a method for dynamically limiting total colorant coverage, the method comprising: defining a first geometric region of a multi-dimensional colorant cube to comprise any colorant combination that exceeds a total coverage limit; defining a second geometric region of the multi-dimensional cube to comprise any colorant combination that is within the total colorant coverage limit; identifying a reference point within the second geometric region to define a third geometric region of the multi-dimensional cube, wherein the entirety of the third geometric region is within the second geometric region; using a resultant color in the color rendering process if an input color falls within one of: (i) the first region; and (ii) the third region; and bijectively transforming the input color of the first region into a resultant color, wherein the resultant color lies within the third region.
