The use of CRT monitors as a soft copy proof in color electronic pre-press systems (CEPS) has become common. This has raised some question as to the appropriate viewing conditions for such terminals. This writing discusses the effects of ambient illumination as well as screen surround conditions on optical, psychophysical, and physical characteristics of CRT colors in a complex color field. A review of related literature, specifically those studies of chromatic adaptation, and effects of surround conditions on brightness, hue, and saturation is included. These studies are compared to the experimental data and both an ambient light model and surround transform are derived.
