A Study of the Effect of Color Photostimulation from a Cathode‐ray Tube (CRT) Display on Photosensitive Patients: The Effect of Alternating Red–Cyan Flicker Stimulation

Abstract

These findings suggest that alternating R/C flicker is more provocative than simple red flicker, and that contrast between frames of different colors may play some role in the effects of alternating flicker stimuli from a CRT display in photosensitive patients. Therefore, caution against the use of the combination of red and cyan, in addition to the red flicker stimulus, should be included in any guidelines drawn up to prevent photosensitive seizures.
