Ohno and others have criticized CRI for not always correlating well with subjective color rendering quality in practice, particularly for light sources with spiky emission spectra such as fluorescent lamps or white LEDs. Another problem is that the CRI is discontinuous at 5000 K, because the chromaticity of the reference moves from the Planckian locus to the CIE daylight locus. Davis & Ohno (2006) identify several other issues, which they address in their color quality scale (CQS): WebThe CRI measures a light source’s ability to reveal the intrinsic colors of the objects it illuminates, referred to as its accuracy, or color fidelity.

WebThe CRI is usually measured on the target and background surface. The radiant contrast is attenuated by atmospheric transmittance and measured using infrared detectors. On the other hand, it is almost impossible to estimate the correct atmospheric transmittance due to the time-varying properties [ 23 ].
