Gaze-Contingent Manipulation of Color Perception
summary
Two experiments test gaze-driven color changes: a color-matching task shows gaze-contingent simultaneous contrast produces shifts similar to static surrounds and sometimes diverges from existing color-appearance models, and a color-sorting task shows performance improves when unseen items are altered but not when only the global background changes. Error rates drop with peripheral patch manipulation and with the combined condition only because patches change, so background-only change shows no benefit.
