The use of color and transparency for attention cuing in complex displays was investigated. The color set used in one such complex display that was developed by the United States Air Force Research Laboratory, the Global Weather Management system (GAMAT/GWM), was altered and compared to a different color set in order to investigate the impact of these color choices. In addition, transparency was introduced into the display. Conspicuity of a red target alert was measured for both color selections with and without transparency cues. Main effects were found for both choice of color set and the transparency conditions. The research shows how a simple laboratory search technique may be used to test chromaticities for use in these and future systems in which particular stimuli need to be rapidly noticed and provides a first step towards the investigation of transparency as a separable visual feature.
