feeling of contrast index (FCI)

There are several characteristic values for the colour representation and rendering of LED luminaires and LED lighting. These include the Correlated Color Temperature (CCT), the Color Rendering Index (Ra), the Color Quality Scale (CQS) and the Feeling of Contrast Index

(FCI). The FCI value is used in the lighting technology of shop windows and retail stores and is aimed at the subjective perception of colour. It is calculated from the ratio between the colour temperature of a test lamp and a daylight lamp with a colour temperature of 6,500 K, standard illuminant D65. The FCI value indicates the colour contrast perceived by the viewer and whether the viewer perceives the colour as unsaturated, natural, saturated or oversaturated.
