Col Res Appl. 2018 Vol. 43: pp. 349-357 Chanprapha Phuansuwan, Mitsuo Ikeda, Janjira Mepean abstract The color appearance of negative afterimages was measured by the elementary color naming method, and the results were compared with those obtained by the two-room technique. Twenty adapting stimuli were presented on a display sequentially. Subjects first assessed the color …

Phuangsuwan C, and Ikeda M. Col. Res. And Appl. 2018 Early View. abstract It is said that we cannot have color constancy in a photograph. The concept of recognized visual space of illumination (RVSI) asserts that chromatic adaptation occurs when one perceives the illumination that is filling a space and not the objects in the …
