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 preuiously cited populations of textile production goods. Thefixed‐grid geometries (cubic, rhombic dodecahedra1 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).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
