Assessing the colour quality of LED sources: Naturalness, attractiveness, colourfulness and colour difference
[ PUBLICATION ]
The CIE General Colour Rendering Index is currently the criterion used to describe and measure the colour-rendering properties of light sources. But over the past years, there has been increasing evidence of its limitations particularly its ability to predict the perceived colour quality of light sources and especially some LEDs. In this paper, several aspects of perceived colour quality are investigated using a side-by-side paired comparison method, and the following criteria: ...

Perceived lighting quality of LED sources for the presentation of fruit and vegetables
[ PUBLICATION ]
The CIE Color Rendering Index (CRI) is the most widely-used measure of quantifying and comparing the color rendering properties of light sources. There is however today a debate concerning the limitations of this index for sources such as LEDs. In this paper we present a new approach to quantifying the visual color quality of light sources. We investigated the color rendering of fruit and vegetables in terms of attractiveness, naturalness and suitability. Perceptions of 40 observers were ...

Colour differences in Caucasian and Oriental women's faces illuminated by white light‐emitting diode sources
[ PUBLICATION ]
OBJECTIVE: To provide an approach to facial contrast, analysing CIELAB colour differences (ΔEab,10∗) and its components in women's faces from two different ethnic groups, illuminated by modern white light-emitting diodes (LEDs) or traditional illuminants recommended by the International Commission on Illumination (CIE).
METHODS: We performed spectrophotometric measurements of spectral reflectance factors on forehead and cheek of 87 young healthy women (50 Caucasians and 37 Orientals), ...

A psychophysical experiment was conducted to investigate the perceived color rendition of facial complexion under different spectral power distributions (SPDs). Sixty-three subjects completed a categorical evaluation of their own skin under 20 light sources at 2700 K (fluorescent and LED), in a full-size booth. The aim was to investigate the influence of SPD on the appreciation of observers of their own complexion. Three different types of skins were evaluated and statistical analyses ...
