"Hunt's ability to transmit complex technical information in a communicable, easy reading manner is to be applauded…will make a difference n the careers of scientists, engineers, color developers, and color technologists, who undertake to study and learn from it." (COLOR research and application, December 2005) "…a standard…[that] is widely used in research, teaching, and lecturing." (CHOICE, July 2005)
