Visibility of Various Target-Background Color Combinations under Different Chromatic Ambient Illuminations

摘要

The detectability of seven colors presented on a CRT against four background colors was measured under four conditions of ambient lighting. Opponent color pairs were most quickly detected. Detection was enhanced by maximizing both luminance and color contrast, but luminance contrast was much more effective. Chromatic ambient lighting which was a log unit dimmer than the target luminance had no effect on performance. (Author)
