It is presently unresolved whether lightnesses or differences in lightness are appropriate independent variables for models of the perceived degree of achromatic transparency. The experiment reported here shows that differences in lightness rather than lightnesses affected the rated degree of transparency and that local changes in differences in lightness altered the rated degree of transparency locally. These results indicate that models of the perceived degree of transparency should be separately formulated for the different parts of a transparent surface and for the whole transparent surface. Two new models of the combined effects of differences in lightness on the perceived degree of transparency are proposed.

Abstract
It is presently unresolved whether lightnesses or differences in lightness are appropriate independent variables for models of the perceived degree of achromatic transparency. The experiment reported here shows that differences in lightness rather than lightnesses affected the rated degree of transparency and that local changes in differences in lightness altered the rated degree of transparency locally. These results indicate that models of the perceived degree of transparency should be separately formulated for the different parts of a transparent surface and for the whole transparent surface. Two new models of the combined effects of differences in lightness on the perceived degree of transparency are proposed.Pubblicazioni consigliate
