This paper uses calculated ΔE*ab values for 730 spectral reflectances, two reference illumination sources, 88 candidate illumination sources, five camera spectral sensitivities and the CIE 1931 observer to determine the degree to which the illumination source metrics CCT, CRI Ra, TM-30 Rf, TLCI and SSI can be used to reliably select candidate sources to avoid color differences with reference sources. The ISO 7589 spectral distribution index and digital camera scene analysis errors are used to determine excellent and very good ΔE*ab criteria. Correlations between the illumination source metrics and color differences are generally poor, but metric values close to 100 predict the small color differences required for cinematography.
