We re-examined Helson's (1938) complementary color which Cohen's (1958) subjects could not observe in his partially inhomogeneous Ganzfeld. We found that even in the Ganzfeld similar to Cohen's, Helson's complementary color can be seen if several slight changes are made. The color appeared twice, just at the moment of the start of observation and again about a min. later, after which it remained almost constant in our experiment. We found that it is this latter color which corresponds to Helson's complementary color, and that it is an afterimage color, not a discounted color or a contrast color.
