Decoding Color Perception: An Eye Tracking Perspective

Eye movements scan objects and features in our environment, with color being fundamental to visual experience. Individual variations in color vision create diverse perceptual interpretations. Eye tracking provides objective quantification of these perceptual differences through fixations and gaze patterns. This review consolidates research on eye tracking methodologies for assessing color discrimination abilities. Metrics like fixation duration, saccadic patterns, and pupillary responses have proven sensitive to variations in color perception. Distinctive eye movement patterns emerge as potential markers for color vision deficiencies, variations in color naming, and how context affects color perception. Eye tracking effectively measures color perception objectively and identifies anomalies in color vision. The technology reveals how individual differences in color processing influence visual attention, offering insights into the relationship between physiological color processing mechanisms and behavioral responses to colored stimuli.
