Abstract:
To investigate whether screen color is an important variable in the prescription of CCTV systems, the author measured the visual performance of CCTV users on white, green, and amber screens. When the screen luminance and contrast were equated for each CCTV, the users' reading performance was unaffected by the screen color. Although some individuals expressed a clear subjective preference or dislike for one color or another, there was no obvious link between the cause of low vision and preference for or aversion to that color.
