Paper Abstract

Jay Hannah has been studying changes in color with distance for a number of years. He has studied this phenomenon by making a series of over 100 paintings. With the keen eye of an artist he has made many dramatic demonstrations of color change. An example is that a 1.2 cm white stripe will appear bright yellow at a distance of 14 meters. Hannah has shown that color is influenced by the surround, but not by the usual complementary color rules. This paper describes a series of experiments that use color matching to quantify the appearance of a number of Hannah's painting at close (1.4 m) and far (14 m) distances This study uses the changes in appearance to establish the visual equivalent at different distances. These equivalent colors can be used to study the underlying mechanism of color appearance near spatial-frequency threshold.
