<p>Amodal completion involves the impression of existence and properties of visually occluded parts of objects. One aspect of this phenomenon that has been somewhat neglected is the amodal completion of color, which involves the impression that amodally completed surfaces have a particular color. In this paper, this aspect is investigated by constructing a large number of displays with identical target figures embedded in systematically varying contexts, to find out which contexts are conducive for amodal completion of color and which are not. In this setup, the main effects of changes of contexts are changes of geometric and photometric features of junctions along the borders of the target regions, which can cause dramatic differences in the appearance of those regions. Generally, a certain arrangement of T-junctions supports the impression of amodal completion of color, and it can be argued that certain types of X-junctions support a variant of this effect as well.</p>
