Abstract
Electronic display colours must be easily discriminated and recognized under different ambient lighting and symbol size conditions. Low level blue and red lighting is used as an alternative to white lighting in some submarines, ships and aircraft. Two studies, one investigating the effects of low level red lighting and stimulus size compared to white lighting and one investigating the effects of low level blue lighting and stimulus size compared to white lighting are summarized. Both red and blue lighting and size influenced the naming of colours, however, ambient lighting had less influence than stimulus size. Colour naming reliability levels for each of the stimuli were plotted on the CIE diagram to provide a basis for deriving colours that are least likely to be confused under different ambient lighting and stimulus size conditions.
