A New Measure of Color Discrimination (No CEU)

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.   
3. Explore an in-depth study of the relationship of gamut area and color discrimination.    
4. Describe the limitations of current color metrics.
