Page:Tristimulus specification of the Munsell book of color from spectrophotometric measurements (IA jresv31n1p55).pdf/28

 NBS color name for a color may be found by the use of any spectrophotometer or colorimetcr [22, 231 whose resultant values may be transformed into data based on the ICI standard observer and coordinate system. Likewise, any color system may be used as a comparison standard if the trilinear coordinates of each sample in that system are plotted on the (x, y)-diagrams and the ISBCC-NBS color name determined through conversion to the Munscll notation.

The authors express their appreciation to Leo G. Glasser, Harry J. Keegan, and Margaret M. Balcom for running the spectral reflection curves on which the data of the present paper are based, and to Davis H. Wilson for directing the tabulating and statistical work on the Hollerith cards. They also acknowledge their indebtedness to the late Walter T. Spry, form er manager of the Munsell Color Co., and to Blanche R. Bellamy, present manager of the Munsell Color Co., who have seen that nothing was lacking in samples or assistance to make this project a success.
