What created the outward movement of different colors in the candle flame and light bulb negative afterimage?
Color to our sight is caused by different wavelengths of light. In my opinion, the color flow in the flame/bulb afterimage was due to the changing wavelengths of light as the energy moved outward from the flame or bulb and created the effect of movement. Can movement be observed when viewing negative afterimages? My experience indicated a moving negative afterimage is never seen because the visual signals for movement occur so rapidly that it does not allow enough time for the negative signals to form in order to be observed. A minimum of five seconds was needed (after many hours of feedback had already occurred) with an absolute steady gaze at an external object before a vivid dominant negative afterimage would form. If there was eye movement or external object movement, no afterimage would form. But as energy radiated out away from the flame or lightbulb created the sensation of movement. Why didn’t the flame’s flickering cause the flame negative afterimage not to form? I believe the
