The light-emitting diodes (LEDs) have become popular, and it is necessary to evaluate the color qualities of LED lighting. Color discrimination is one of the important aspects of color qualities at museums, stores and so on. In this study, we compared two types of 100-hue test under LED and conventional lightings to examine the influence of test samples, especially saturation on the evaluation of color discrimination. One was ND-100 (average = 13.43), the other was Farnsworth-Munsell 100-Hue Test (average = 25.67). The colors of test lights were daylight, neutral white, and incandescent color. Observers performed two types of 100-hue test under all test lights. Results show that the trend of color discrimination in ND-100 and Farnsworth-Munsell 100- hue test are similar, and there is a little difference between LED and conventional lights in general.
