Twenty-two measures of color rendition have been reviewed and summarized. Each measure was computed for 401 illuminants comprising incandescent, light-emitting diode (LED) -phosphor, LED-mixed, fluorescent, high-intensity discharge (HID), and theoretical illuminants. A multidimensional scaling analysis (Matrix Stress = 0.0731, R(2) = 0.976) illustrates that the 22 measures cluster into three neighborhoods in a two-dimensional space, where the dimensions relate to color discrimination and color preference. When just two measures are used to characterize overall color rendition, the most information can be conveyed if one is a reference-based measure that is consistent with the concept of color fidelity or quality (e.g., Q(a)) and the other is a measure of relative gamut (e.g., Q(g)).
已对22种显色度量进行了回顾和总结。针对包括白炽灯、发光二极管（LED）-荧光粉、LED混合、荧光、高强度放电（HID）以及理论光源在内的401种光源计算了每种度量。多维缩放分析（矩阵应力=0.0731，R(2)=0.976）表明，这22种度量在二维空间中聚为三个邻域，其中维度与颜色辨别和颜色偏好相关。当仅使用两种度量来表征整体显色性时，如果一种是与颜色保真度或质量概念一致的基于参考的度量（例如Q(a)），另一种是相对色域的度量（例如Q(g)），则可以传达最多的信息。
