bias lighting in terms of color perception
As a general recommendation, the correct color temperature is going to align with video industry standards and best practices. Since we are in the calibration section of the forum, where picture accuracy is the dominant objective, one could assume that participants have or plan to provide the recommended neutral colored surrounding surface for the ambient lighting to reflect from. It's the illumination reflected by the wall that determines how a viewer's color perception of the display's image will be affected. These video fundamentals are discussed in the "sticky" thread section at the beginning of this area of the forum.
Education in video fundamentals is sorely lacking in the consumer video arena. Most consumers rely on a haphazard accumulation of video knowledge or just grope their way through designing their entertainment system by intuition. If intuition (what an individual viewer decides they "like") is the rule, AV science remains a foreign interest. When imaging science is the focus, a viewing experience approaching reference quality becomes attainable. Generally speaking, most consumers never get there. Their enjoyment of the beautiful images our advanced state of HDTV has enabled is minimized.
Only a cursory awareness of the purpose of video bias lighting for many hobbyists has resulted in the frequent focus on alleviating eye strain alone. When the video industry recommended practice documents are studied, it is found that the prevailing focus deals with preserving correct color perception, much more than viewing comfort. Seeing the image correctly has the profoundly greater emphasis. Seeing an authentic picture is the priority for those interested in display system calibration and proper equipment setup. Whether someone has ever died in the process rarely comes up, in my experience.
