Development of a perceptually relevant color rendition measure for better evaluation of lighting quality

Background:
Nowadays, spectrally narrowband light sources (e.g., light-emitting-diode (LED), quantum dot and laser-based lighting) are widely used in lighting design and displays due to their wide-gamut and high energy efficiency. However, the different characteristics of these light sources compared to conventional light sources and particularly the diversity of light spectra produced make it challenging to assess their colour quality
