By using the color adaptation procedure,we compare the difference of color appearances in normal color sense and extrasensory perception (ESP) color sense (recognition by finger condition). We find that,the subject,who has ESP ability,can keep color constancy in normal visual condition after red-light adaptation,but not in recognition by finger condition. This result suggests that ESP color vision may be illuminated by external light source through the normal visual pathway. We discuss the possible relationship between properties of special screen in ESP color vision and brain activity in last paragraph.
