Pont de Nemours and Company in Troy, Michigan is being recognized for his outstanding contributions to the advancement of industrial color difference metrics.
During the middle 1980s, Dr. Alman recognized a need for an improved color-difference equation in comparison to then widely used equations such as FMCII, HunterLab, and CIELAB. The CIELAB equation is currently recommended for use by the International Commission on Illumination (CIE). Weighted CIELAB color-difference equations, including JPC79 and CMC, provided further evidence of the inadequacy of CIELAB, especially for setting color differences and tolerances. Both the JPC79 and CMC equations were based on textile data and might not be appropriate for the automotive coatings manufactured by DuPont. Accordingly, Alman obtained funding and began a research initiative with RIT's Munsell Color Science Laboratory (MCSL). Dr. Alman was largely re-
