We assessed the advantages of a color-coded weapons symbology for a helmet- mounted display over monochrome symbology by measuring military pilots' per- formance while they flew air-to-air combat in a simulator The pilots fired missiles significantly sooner without sacrificing probability of kill when using the color- coded symbology demonstrating a substantial practical benefit of color. Actual or potential applications of this work include the design of color codes for helmet- mounted and other displays that use complex symbology to assist performance on cognitively challenging tasks.
