Metrics in Motion: Color Metrics

About this Course

The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. Metrics in Motion: Color Metrics was a live webinar, now available as an archived webinar and CEU course.

Description: After decades of debate and living with limitation, new color metrics for both color rendition and chromaticity have been standardized by the IES and/or CIE. While science has advanced, the practice has been slower to evolve. This webinar will look at recent developments and how they might change lighting practice over the next 10 years. It will demonstrate how all constituents in the lighting community can benefit from using metrics that fit the capabilities of today’s lighting technologies. Manufacturers can more effectively evaluate performance tradeoffs and communicate product performance, allowing differentiation with novel products; specifiers can reduce uncertainty and avoid unsightly consequences, and researchers can use improved methods to investigate fundamental lighting science challenges.

Learning Objectives:

By the end of this course learners will be able to...

1. Understand the history of chromaticity (color of light) measurement and utilize descriptors of it.   
2. Explore concepts of color rendition including metamerism and chromatic adaptation. 
3. Understand the basics of TM-30, and new supplemental information including Annex E. 
4. Learn recommendations and limitations of color criteria in specification.

Michael Royer, PhD

Dr. Michael Royer is a senior engineer at the Pacific Northwest National Laboratory (PNNL), where he works on the Advanced Lighting Science and Technology Research program, sponsored by the U.S. Department of Energy. His primary research area is human factors in lighting. He conducts experiments to help refine metrics and specification guidance, with the ultimate goals of advancing lighting quality to improve building occupants’ satisfaction and increasing the use of energy efficient lighting technologies. Michael is co-chair of the Illuminating Engineering Society (IES) Vision Science committee and a member of the Color Committee. He also serves on the International Commission on Illumination (CIE)-U.S. National Executive Committee and other CIE technical committees. He is an associate editor for the journal Lighting Research & Technology. Prior to joining PNNL, Michael earned a Ph.D. in Architectural Engineering from Penn State University, receiving the 2013 Taylor Technical Talent Award from the IES for his published work, which focused on tuning optical radiation for visual and nonvisual effects.
