Poster Session: On the relationship between chromatic sensitivity and vividness of illusory colored signals

Color perception is an integral skill of vision aiding rapid segregation and categorization of objects in the environment. It depends on both low-level spectral analysis of the light reflected by an object and high-level interpretation of the retinal output. Although, interindividual differences in color perception can be mostly negligible in real life environments, there is some indication that these differences can be quite substantial when color appearance is considered. We developed a series of experiments with participants completing color matching tasks of illusory colored stimuli while also evaluating their individual chromatic sensitivity using a standardized color assessment test. Our results highlight large variability in color appearance with this variability being inversely related to the individual chromatic sensitivity. Furthermore, our data provide hints for the potential use of chromatic illusions in the assessment of interindividual differences in colour processing.
