Impact of solid-state lighting on observer performance of color discrimination

We studied the impact of the microscope light source on reader's performance using a microscopic version of the Farnsworth-Munsell 100 hue test for photographic slide film. Each pair of two adjacent color caps in the original test kit was reproduced on the film with random order and a 5X objective was used to examine the microscopic color patterns. The subject's visual task was to determine whether the color pair was in the correct hue order or not. The test was repeated for both a light-emitting diode lamp and a conventional halogen lamp. In this paper, we discuss the methodology using preliminary results.
