This research aimed to investigate the effect of neighboring colors on color appearance. The psychophysical experiment was carried out in a dark room by using D65 standard lighting booth. Total of 5 different neighboring color conditions were used in the experiment and those were 'Reference', 'Desaturated', 'Saturated', 'Dark', and 'Light'. Total of 20 participants were invited to each neighboring color condition. Each participant evaluated hue, colorfulness, and lightness of 22 test colors by using magnitude estimation method. Result found that colors shown with the low chroma neighboring colors look more colorful and when the neighboring colors have high lightness, colors look less colorfulness and darker.
