A Review and Assessment of Numerical Shade Sorting Methods

The properties of current shade sorting geometries are evaluated on a mathematically generated spherical population of normally distributed data points. The results compare well with those obtained from previously cited populations of textile production goods. The fixed-grid geometries (cubic, rhombic dodecahedral and truncated octahedral) are not as efficient in terms of the numbers and uniformity of shade sorting groups as the grid-free spherical clusters employed by Clemson Color Clustering (CCC)
