To help the lighting industry develop and implement new color-rendering methods and metrics that address the shortcomings of the commonly used CRI metric, the U.S. Department of Energy conducts research to enhance understanding of color rendition. An article based on this research, “Chroma Shift and Gamut Shape: Going Beyond Average Color Fidelity and Gamut Area,” was recently published in the journal LEUKOS.
The article discusses two concepts in color rendition–gamut shape and chroma shift–recently formalized in IES TM-30-15, Method for Evaluating Light Source Color Rendition. It discusses the calculation methods for these evaluation tools, how to interpret the values, and the ways in which these tools provide far more information about color rendition than average measures.
