Abstract

The first results of a novel visual experiment for the analysis of the appearance of colours under different lights is presented. It could be the basis for the improvement of the Colour Rendering Index, starting from the concept of unique hues. The constancy or variations of unique hues could be used to analyse colour distortion introduced by different contents in the spectral density power of the light source under test. Among the sources analysed in the experiment are incandescent lamp, a simple realization of D65 and white LEDs.
