    "abstract": "As solid state lighting (SSL) sources have gradually replaced tungsten sources, new challenges in color rendition have emerged. CRI is often quoted for sources but is limited to a human observer, without purporting to predict potential color differences for cameras. A new color index is proposed that is based upon the similarity of a luminaire's spectrum to a reference spectrum that eliminates the need for any assumption of a specific observer or camera spectral sensitivity. The index yields a “confidence factor,” where a high score implies predictable color rendition for cinematography, and a moderate score implies possible color rendition challenges.",
