To clarify more physically the quality of visual sensation known as complementary color after image, we compared the change in CFF values under complementary color after image and under same color of the real light given as surrounding light. The tendencies of both changes were roughly as follows: (a) when the color of flickering light and complementary color after image and also surrounding light were similar, the values of CFF decreased monotonically with increasing brightness of complementary color after image and surrounding light. (b) When the color of flickering light and complementary color after image and also surroundig light were complementary the values of CFF increased in the higher brightness range of complementary color after image and surrounding light. Therefore we conclude that the effects of changing CFF values are controlled by the "color adaptation mechanisms" not only in the case of real surrounding light but also that of perceptual quantity of complementary color after image. Moreover by applying Ferry-Porter's law to result(a), we were able to roughly estimate the effects of changing CFF values due to the perceptual quantity of complementary color after image by the effects due to physically measurable quantities such as flickering frequency and light brightness.
