Flavell, Richard and Heath, A. (1992): Further Investigations into the Use of Colour Coding Scales. In Interacting with Computers, 4 (2) pp. 179-199.

“The use of colour in computer-generated displays is increasingly common. This paper reports on controlled experiments into the quantitative use of colour using coding scales. Three experiments are described, investigating respectively: * The impact of the number of divisions in a perceptually uniform scale. This showed that errors increased as the numbers of divisions increased, but maximum information transfer actually occurred with about 10 divisions. * The feasibility of constructing scales with a constant spread of incorrect responses for any given stimulus. The overall findings were inconclusive although as a by-product it is statistically suggested that errors are exponentially rather than normally distributed. * The impact of a small number of perceptual discontinuities within an otherwise perceptually uniform scale. It was found that observers did not make response errors that crossed the discontinuities, however their error rate between discontinuities increased. Finally some applications are described.”

Laar, Darren Van and Flavell, Richard (1988): Towards the Construction of a Maximally-Contrasting Set of Colours. In: Jones, Dylan M. and Winder, R. (eds.) Proceedings of the Fourth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers IV August 5-9, 1988, University of Manchester, UK. pp. 373-389.

“Two experiments are reported. The first investigates the relationship between hue, lightness and saturation in determining colour contrast in displays, the second examines the effect of surrounding and adjacent colours on the perception of stimuli in colour displays. All subjects taking part in the experiments had normal colour vision. Hue difference between stimuli was found to exert the biggest single effect on colour contrast, with similar hues being discriminated significantly more slowly than different hues. Lightness difference also produced a significant effect in the same direction. Saturation effects were surprising in that more similar saturations were associated with significantly faster reaction times. In the second experiment strong brightness and hue context (induction) effects were observed but effects due to target size and saturation did not reach significance. The relevance of these findings to designers of colour displays is discussed.”
