Colour electronic displays are being used increasingly for information presentation in a wide range of applications. A prerequisite to the effective use of colour coding is that the colours be discriminable under all of the conditions in which the display will be used. For applications such as radar, medical imaging, or electronic charts, different coloured areas may be juxtaposed and coloured symbols superimposed on a multicoloured background. Under such conditions, the colours in the display may affect the appearance and discriminability of each other. the present article examines the extent to which a set of colours that is clearly distinguishable when presented against a uniform background might be confused when the members are presented against differently coloured backgrounds. This was achieved by measuring the range of chromaticities, presented against a grey background, that would be confused with each of the test colours when they were presented against different chromatic surrounds. the findings were used to derive the characteristics of sets of colours that should be discriminable in a complex display.
