RT Journal Article T1 Theoretical considerations on small color differences ascribed to the standard observer made on the basis of individual color-matching functions A1 Carreño Sánchez, Fernando A1 Ezquerro Rodríguez, José Miguel A1 Zoido Chamorro, Jesús Manuel AB An analytical method to determine how color-matching functions influence the perception of chromaticity differences is proposed. We show that, as a consequence of the observer metamerism, a metameric color-match perceived by one observer may appear to be a significant mismatch to a different observer. It is also shown that, on average, the differences between the color-matchings made by two different observers can be estimated to be in the order of 2 CIELAB units. PB John Wiley & Sons, Inc.
