Recently, the number of cases in which colored films are put on vehicles or residential windows is increasing to prevent hot summer heat and UV lights inducing skin cancer and aging. However, colored films with a high blocking rate may cause the color constancy, a phenomenon of subjective color appearance. When the film is applied in the wrong way, or part of it is damaged and missing, an optical illusion can occur between the surfaces with and without the film, which leads to confusion and even to an accident. In order to prevent such confusion and potential accidents, we performed color perception experiments according to the color and transmittance, based on which the degree of errors of color perception were derived. Thus, in this study, we identified the tendency of color constancy based on color and filter transmittance rates, and we quantitatively analyzed the degree of errors in color perception by measuring hue, brightness, color purity, and color difference in the Munsell color system.
Our experiments were carried out in a space without windows in order to exclude the potential effects of daylight and surrounding artificial light. The inside of the experimental space was finished with N9.5 white (S0500-N) paint. A D65 standard light source was installed on the ceiling. In the experiment, we presented the object in which five different colors such as R, Y, G, B, and P with transmittance rates of 25%, 50%, and 75% were thrown onto the same picture. Subjects were asked to find a color in which a particular shape of N5 was perceived in the Munsell color system and then to write the hue, brightness, and color purity on the evaluation sheet. In addition, we derived a color difference between N5 (original color) and the color that was perceived due to the optical illusion. Thus, we identified the filter color causing the optical illusion the most frequently and the filter transmittance rate.
