A psychophysical experiment was conducted to evaluate the performance of various colour spaces, colour difference formulae, colour matching functions and colour fidelity measures in predicting perceived colour differences. Ten observers evaluated the colour differences of 20 colour samples under 11 pairs of light sources. The results suggest that the colour differences calculated using the CIE 1964 colour matching functions in the CAM02-UCS colour space can predict the perceived colour differences. IES-Rfwhich used the 20 colour samples and the reference illuminants used in the experiment was highly correlated to the perceived colour difference. The importance of a uniform spectral sensitivity for colour fidelity measures is also identified.
