Color designations below refer to the Royal Horticultural Society Colour Chart, 1966, unless otherwise stated. When R.H.S. Colour Chart (1966) numbers are used, the color names preceding these numbers are those of the Universal Color Language (ULC) or Inter-Society Color Council National Bureau of Standards (ISCC-NBS). Coordination of the names and numbers is published in A Contribution Towards Standardization of Color Names in Horticulture: Application of the Universal Color Language to Colors of the Royal Horticultural Society's Colour Chart , by Robert D. Huse and Kenneth L Kelly, edited by Donald H. Voss, ARS Publications Committee, 1984.
