Two novel experiments for the analysis of the effect of different lights on the appearance of colours are presented. They could be the basis for the improvement of the Colour Rendering Index. The first experiment starts from the concept of unique hues and analyses the constancy or variations of unique hues under different real light sources. The second experiment deals with colour difference and allows to evaluate local distortion of the colour space. Analysed sources include incandescent lamp, a simple realization of D65 and white LEDs. The samples used in the experiments are three dimensional to reproduce more realistic conditions.

Abstract
Two novel experiments for the analysis of the effect of different lights on the appearance of colours are presented. They could be the basis for the improvement of the Colour Rendering Index. The first experiment starts from the concept of unique hues and analyses the constancy or variations of unique hues under different real light sources. The second experiment deals with colour difference and allows to evaluate local distortion of the colour space. Analysed sources include incandescent lamp, a simple realization of D65 and white LEDs. The samples used in the experiments are three dimensional to reproduce more realistic conditions.
