Substantial advances in color science have been made over the past several years, most notably IES TM-30 and IES TM-30 ANNEX E. Importantly, no measures of color rendition, standardized or otherwise, consider the impact of light level on color rendition. This is important because objects appear less colorful at low light levels than at high light levels—a visual phenomenon known as the Hunt Effect. Despite the many lighting applications where low light levels are common and color rendition is important, current lighting solutions do not account for the change in color sensitivity as a function of light level. A strategy for overcoming the Hunt effect with LEDs will be discussed and a pictorial demonstration will be provided.
