Research on the impact of light source spectrum on color vision

Abstract

This paper studies the impact of light source spectrum on color vision using indoor simulation experiments. Under the same condition of illuminance, a test participant observed different color pictures under light sources in black boxes respectively. The impact is studied by the distance that a test participant distinguishes the color brightness difference in each picture. It has been found that there’s impact of light source spectrum on distinguishing the brightness difference of some colors. And color rendering index can be an important factor in the distinguishing process.
