 CQS (Color Quality Scale by NIST Recommending)
- A Color Quality Scale (CQS) is being developed at NIST with input from the lighting
industry and the CIE (International Commission on Illumination) to address the
problems of the CIE Color Rendering Index (CRI) for solid-state light sources and to
meet the new needs of the lighting industry and consumers for communicating color
quality of lighting products.
The CQS uses a set of 15 Munsell samples, as shown in Figure 2.
These samples have the much higher chroma, span the entire hue circle in
approximately even spacing, and are commercially available.
