When purple perceived only at fixation: A fixation- and distance-dependent color illusion
Abstract
In this paper, an optical illusion is described in which purple elements are perceived as purple at the point of fixation, while surrounding elements of the same purple color are perceived toward a blue hue. As the viewing distance increases, a greater number of purple elements revert to a purple appearance.
