  • A New Measure of Color Discrimination

    Contains 4 Component(s), Includes Credits

    This presentation will summarize the previous literature on color discrimination and discuss recent work in this area. A recently published study by the current speaker will be discussed, which dispels the conventional wisdom that gamut area is a predictive color discrimination metric.

    About this Course

    The IES offers a series of webinars that provide supplemental education to coincide with a recently revised or new IES Standard (Recommended Practice - RP, Technical Memorandum - TM, etc.). TM-30, in 2018 and Beyond: Guidance for Improving Color Quality is part of the IES Standards Webinars

    Description: Color rendition is commonly considered within three conceptual frameworks; color fidelity (the rendition of objects such that they appear as they would under a familiar reference illuminant), color preference (the rendition of objects such that they appear pleasant, vivid, or flattering), and color discrimination (the ability to distinguish colors of slightly different hue when viewed simultaneously). Color discrimination has been studied less frequently than color fidelity or color preference, though it is no less important. This presentation will summarize the previous literature on color discrimination and discuss recent work in this area. A recently published study by the current speaker will be discussed, which dispels the conventional wisdom that gamut area is a predictive color discrimination metric. This presentation will detail a new measure of color discrimination, which shows strong predictive ability of experimental results.

    Learning Objectives:

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

    1. Explore a method of modeling color discrimination and color rendition.   
    2. Understand elements of color rendition, and TM-30.

  • Metrics in Motion: Color Metrics

    Contains 4 Component(s), Includes Credits

    This webinar will look at recent developments in the specification and evaluation of color rendition including an overview of TM-30-18 and subsequent developments. How those developments could change lighting practice over the next 10 years will also be explored.

    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.

    About this Course

    The IES offers a series of webinars that provide supplemental education to coincide with a recently revised or new IES Standard (Recommended Practice - RP, Technical Memorandum - TM, etc.). DG-1, Design for Color and Illumination is part of the IES Standards Webinars

    Description: When developing a lighting design, lighting specifiers determine the lamp and fixture combination that best suits the design’s requirements based on many factors. While some considerations are largely technical, such as power consumption, the amount of light generated, and how light is distributed, one consideration is both technical and artistic and can be approached in a number of ways. 

    Learning Objectives:

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

    1. Describe the three common color specification criteria: CRI, CCT, and TM-30.   
    2. Develop an understanding of how color goals translate to specifications.    
    3. Explore human perception in the relationship of color & illuminance levels.   
    4. Develop a confidence in relying on specific measurement and performance standards available in the light & color space.
