Monitor based color assessment is a common approach for visual experiments that became more popular during the COVID-19 pandemic. The objective of this study was to compare the color difference evaluation of the material in the physical object form against the reproduced image of the stimuli on the monitor. A psychophysical experiment was designed to evaluate the effect of viewing mode on perceived suprathreshold small color differences and the intra- and inter-observer variability associated with this type of experiment. The viewing conditions and viewing geometry was evaluated to make sure a similar viewing environment was maintained for evaluating the physical sample and reproduced their image on the monitor. The results suggest that the intra and inter-observer variability for two viewing modes are not statistically different. STRESS index and conventional statistical studies suggest that the color evaluation of the textured samples in the form of physical samples and the image reproduced on the monitor is not statistically different. Calculated color differences based on color appearance models such as CAM02-UCS and CAM16-UCS show the best agreement against the visual color differences for these viewing models.
