The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 12 basic color terms and a small set of adjective modifiers. This system formally defines a set of non-technical color names as a subset of the Munsell System.
I was curious about using this in some data analysis, but I was unable to find a description of the ISCC-NBS system's color lookup tables in machine-readable format, so I've transcribed the information out of NBS Special Publication 440 "Color: Universal Language and Dictionary of Names" by Kenneth L. Kelly and Deane B. Judd into an XML-based document that can be used as an input source for any programming language for which libraries dealing with Munsell notation exist (for example, Colour for Python).
