Earlier findings showed that redundant colour coding decreased response times and reduced errors in carrying out various tasks that required information acquisition from the video desplay of an electronic flight instrument system. The results of this experiment showed that observers with defective colour vision have slower response times and higher error rates than normal observers for some of the tasks and that their performance is similar to that of colour‐normal observrers for a monochrome display. Howerver, they were not disadvantaged when blue was used to colour code thae target feature. Protanopes were shown to be especiall disadvantaged in responding to a red ‘fail’ message.
