The colour differences computed using three advanced formulae have been compared for numerical standard/sample pairs located at regular intervals throughout the colour space. A ratio method was used to compare the values obtained, so that the regions of the colour space where the greatest disagreements occur could be identified. The level of disagreement between the BFD and the CIE94 formulae was generally lower then that between the CMC and CIE94 formulae. In the latter case, the greatest level of disagreement covered a large part of the colour space, concentrated especially in the orange region. It is recommended that studies of the performance of these formulae in relation to visual assessments are made, for real standard/sample pairs located in this region.
