Figure 1.

Processing of color distributions in a scene. (a) Objects of a certain color (blueberries) may be spatially interspersed with other colors in a scene (foliage). (b) A simplified illustration of different color signals within a scene, with each bell curve representing one noisy color signal in the hue dimension. Combining the signals into an estimate of the mean hue, the visual system might either (c) form an internal representation with separate peaks for the different color distributions or (d) combine all signals into an estimate of the grand mean.
