Figure 1

Changes in color appearance predicted by increasing lens pigment density. (a) The original image, as seen by a reference observer assumed to have lens density characteristic of a 12-yr old. (b) The same image filtered through a lens characteristic of an average 72-yr old. (c) The filtered image as it would appear to the same visual system but with the cones adapted to the change in the average incident spectrum. Palettes below the images show the predicted changes in the Munsell array from the World Color Survey.
