Dependence of the Color Rendering Index on the Luminance of Light Sources and Munsell Samples

In this work, the relation between the lighting levels (luminance) and the color properties (color rendering) for both the source and the surrounding represented by the Munsellʹs sample has been obtained. From the analysis of the experimental and calculated data one can show that to obtain good visual performance associated with good color rendering, one must choice lamps with higher luminance value in particular in the case of fluorescent lamp
