This presentation will describe the process and results of the IES Color Metric Task Group's work to develop a recommended color rendition metric. Group members will be present to discuss the novel features of the evaluation system, how it compares and relates to other ongoing efforts, best practices and remaining limitations, and the path forward as the lighting industry transitions from existing metrics to more complete and accurate measures. A tutorial will be provided so that various constituents are comfortable in calculating values and interpreting the results.
