Abstract

Color rendering indices are the most common metric used by the lighting industry to represent the color rendering properties. Color rendering indices are regarded as characteristics of an artificial light source and depend on spectral power distribution of the light. The observed color appearance of objects in a room are affected by not only artificial light but daylight and interreflected light, therefore color rendering properties should be calculated from spectral power distribution of the incident light on objects.<br>The purpose of the paper is to evaluate color rendering properties of daylighting with artificial lighting by calculating spectral interreflection. The result shows quantitatively that color rendering properties degrade in the room with light-colored walls, and the daylighting with artificial lighting improves color rendering properties.
