We investigated whether color constancy depends on task demands by comparing a selection task with an adjustment task. The tabletop was covered with a black cloth, and eight OSA-UCS samples occupied the eight non-central cells of a 3×3 grid. The central cell was reserved for the task stimulus. In the selection task, a test chip was placed at the center and observers chose the sample that appeared to be white paper. In the adjustment task, observers tuned a display patch at the center until it appeared to be white paper, viewing the patch through an aperture in the cloth. Illumination chromaticities were identical across tasks—white, yellow, blue, green, and purple—and were programmed with a projector. Analysis with the color constancy index BRφ indicated that task type modulates the degree of color constancy. |
