Claim One:
1. A method for identifying a set of sample points specifying a color transformation, comprising: identifying a subset of points from a superset of points representing a colorimetric relationship using a processor, wherein the subset of points define an n-simplex with (n+1) points representing an approximation of the colorimetric relationship, n representing a number of dimensions; selecting an additional point from the superset of points using the processor and adding the additional point to the subset of points to replace the n-simplex with a set of at least two n-simplices, wherein the additional point is selected such that an (n+1) volume of an (n+1)-simplex formed by the (n+1) points of the initial n-simplex and a functional value of the additional point is increased; and determining an error value for the approximation by calculating an error volume between the (n+1) simplex and the superset of points.
