Detailed Analysis of Color Shifts

We will now have a detailed look at the performance of the algorithm described in Section 11.2 on the entire set of experiments. Table 14.5 shows the results for four different illuminants and three different backgrounds. The data is shown in the same format as Table 14.1 in order to compare the theoretical results with the experimental results obtained by Helson better. If we compare the two tables, we see that the results correspond exactly to the data obtained by Helson. If the reflectance of the patch is higher than the reflectance of the background, then the patch appears to have the color of the illuminant. If the reflectance of the patch is equivalent to the reflectance of the background, then the patch appears to be achromatic. If the reflectance of the patch is lower than the reflectance of the background, then the patch appears to have the complementary color of the illuminant.
