How Light Affects the Colors of Objects

Aug. 6, 2008 - PRLog -- Color rendering index (CRI) is a system derived from visual experiments. It assesses the impact of different light sources on the perceived color of objects and surfaces. The first step is to determine the color temperature of the light source being rated. Next, each of eight standard color samples is illuminated—first by a light source and then by a light from a blackbody matched to the same color temperature. If none of the samples changes in color appearance, the light source is given a CRI rating of 100. Any changes in color appearance which do occur result in a lower rating. The CRI decreases as the average change in color appearance of the eight samples increases. Any CRI rating of 80 or above is normally considered high and indicates that the source has good color properties.
