No / In this study human color constancy was tested for two-dimensional (2D) and three-dimensional (3D) setups with real
objects and lights. Four different illuminant changes, a natural selection task and a wide choice of target colors were used.
We found that color constancy was better when the target color was learned as a 3D object in a cue-rich 3D scene than in a
2D setup. This improvement was independent of the target color and the illuminant change. We were not able to find any
evidence that frequently experienced illuminant changes are better compensated for than unusual ones. Normalizing
individual color constancy hit rates by the corresponding color memory hit rates yields a color constancy index, which is
indicative of observers¿ true ability to compensate for illuminant changes.
