A Contribution Toward Standardization of Color Names in Horticulture,
Application of the Universal Color Language to the Colors of the Royal
Horticultural Society's Colour Chart, by Robert D. Huse and Kenneth L.
Kelly, Edited by Donald H. Voss. The American Rhododendron Society
Publications Committee 1984. Although this is an old publication, it is
worth knowing about. One of the tables lists the RHS Colour Chart
numbers with their corresponding ISCC-NBS color names and numbers,
Munsell notations, HCC colour names and numbers and CIE chromaticity
coordinates (x, y) and Daylight Reflectance (Y).
