What is ‘white’ light? How is it defined? What is Duv? How can products with the same CCT appear different? What exactly are MacAdam Ellipses? What is color rendering, holistically, and what are the drawbacks of CRI? What is a multi-metric system and what is IES TM-30-18? These questions, and many more, will be addressed in this comprehensive talk about color science. This session is designed for the lighting professional who finds it difficult to navigate the current state of color science and is looking to cut through the fog. This session will present technical information in an easy-to-digest manner and attendees will leave with a much stronger understanding of color science and associated metrics (many of which you may already use!). Current trends in color science research will be discussed, IES TM-30-18 Specification Guidance will be provided.

After this session, lighting professionals/specifiers will be better equipped to interpret colorimetric information and better suited to request color information from the manufacturers they work with. By increasing our understanding of color science, expanding our vocabulary, and fostering constructive dialogue about color specification, the quality of our lighting solutions will be enhanced and the overall benefit of lighting design will be elevated.


Wendy Luedtke, ETC
Ms. Luedtke is the product technology specialist for color at ETC and is a member of its Advance Research Group (ARG). She is the chair of the Color Committee for the Illuminating Engineering Society of North America and a member of the ESTA-TSP Photometrics Working Group and United Scenic Artists Local 829. Previously, she was the product manager for color and lighting at Rosco Laboratories, Inc.

Ms. Luedtke has more than 15 years of experience designing lighting for theater, live entertainment, corporate events, and architectural projects. She holds a BFA in Technical Production from New York University’s Tisch School of the Arts, where she later served for more than a decade as an adjunct instructor.

Tony Esposito, Lyralux
Tony graduated from Penn State University in 2016 with a PhD in Architectural Engineering and a minor in statistics. His dissertation explored human responses to various light spectra with strategically varied average fidelity, average gamut, and gamut shape. His research offers an improved method for predicting color discrimination, validation of several trends in color research, and a simplified method for the quantification and specification of gamut shape.

Tony has won the Robert J. Besal Scholarship four times, received EP funding to attend the IES and IALD annual conferences, and previously served as a graduate fellow on an education grant from the National Science Foundation. He has delivered several guest lectures on lighting fundamentals and design, and has lectured nationally and internationally on color science.

Tony currently serves as a voting member on the IES Color Committee, IES Educational Material Review Committee, and the IES Annual Conference Steering Committee. He is currently the Principal Scientist at a young startup called Lyralux
