The report covers an experiment to determine the effects of target color and brightness contrast on visual detection performance by means of the unaided human eye. The data consist mainly of elapsed times between search initiation and correct detection of tank targets at a simulated slant range of about 1 mile. Statistical methods are employed to assess the effects of color with three levels of contrast factor on detection performance. Under the experimental conditions, effects due to color and brightness contrast were each statistically rated, with the observation that interaction effects between these two factors were not statistically significant. The effect of color tended to account for more variance than the effect of brightness contrast.
