Abstract
Systems and methods are described for adjusting the color spectrum of synthetic objects in augmented reality (AR) displays under varying lighting conditions and a human observers spectral sensitivities, to produce customized color matches for a specific observer. Spectral data may be captured, and color matching functions (CMFs) of the observer may be used by a spectral color workflow that produces color display values, for example coordinates in RGB space. The color rendering may custom-match for multiple observers with different color perceptions under a wide range of environmental (ambient lighting) conditions.
