Organic EL (OLED) has been attracting attention as a next-generation lighting fixture that can achieve high energy efficiency. One of the advantages of OLED is that there is a lot of flexibility in terms of choosing which organic materials to use, which in turm creates various spectral distributions of light. For this purpose, it is important to evaluate the performances of color perception under OLEDs. In this research, we measured the color discrimination performance under a prototype OLED light and compared the results with those derived under fluorescent light and under a commercially available LED lamp. Some observers had more difficulty discriminating color under OLED compared with under D65 fluorescent light. Although the spectral distributions of the light sources were different, the performances did not indicate any statistically significant hue dependences.
