Abstract
Twelve observers naive in relation to McCollough-type phenomena reported subjective colors when viewing a figure consisting of four wedges of dark bars on white, each wedge being oriented at 90 deg to each other wedge. A desaturated reddish-pink was reported for the vertical wedge and a desaturated green-blue for the horizontal wedge. These effects occurred without prior adaptation to color and were orientation specific.
