Description
Summary:Observer metamerism refers to a situation in which some observers with normal color vision will see two colors as identical while others will see them mismatch. In recent years, some issues with metameric failure have been exacerbated by displays with more saturated primaries and narrower emission spectra. Classic trichromatic colorimetry is incapable of predicting this effect because of the typical reliance on a single standard observer—a single color matching function (CMF) averaged across the population. In this paper, we present a new experiment aimed at measuring the amount of metameric failure of a single display for real observers without comparisons to other reference displays. We also propose a recommended metric of observer metamerism failure potential that uses simulated observers, represented as individual CMFs that match the distribution of color sensitivities in the general population, and compare with several other procedures.
