The Color-Rendering Index (CRI) for light source is a quantitative measure of the capability to preserve color appearance of illuminated objects. Recently, CRI has had a renewed interest because of the new LED systems, which usually have a CRI rather low, but a good preservation of color appearance and a pleasant visual appeal. This article presents an experiment performed by human observers to assess the appearance preservation of colors under a set of light sources. Results are then compared with a range of available color rendering indices, in order to assess CRIs variability relative to human judgment.

Abstract
The Color-Rendering Index (CRI) for light source is a quantitative measure of the capability to preserve color appearance of illuminated objects. Recently, CRI has had a renewed interest because of the new LED systems, which usually have a CRI rather low, but a good preservation of color appearance and a pleasant visual appeal. This article presents an experiment performed by human observers to assess the appearance preservation of colors under a set of light sources. Results are then compared with a range of available color rendering indices, in order to assess CRIs variability relative to human judgment.
