A lighting arrangement configured to illuminate an object, the lighting arrangement comprising a plurality of light sources arranged to emit a mixed light of a plurality of colors; characterized in that the lighting arrangement further comprises: - a detector adapted to detect a color and shape of the object to be illuminated; - a database comprising a plurality of pre-stored reflection spectra, color and shapes of objects, a plurality of illumination spectra of said plurality of light sources stored with control parameters for each of said illumination spectra, and results of computations of the color rendering index for each of said illumination spectra; - a control unit in communication with said detector and said plurality of light sources, wherein the control unit is configured to: receive a reflection spectrum of the object to be illuminated by identifying said object through the detected color and shape of the object and by acquiring the reflection spectrum of said object from said database; select, from said database, control parameters for controlling the mixed light emitted by the plurality of light sources such that the mixed light has an illumination spectrum matching the received reflection spectrum of the object and such that a predetermined minimum color rendering index level is achieved; and control said plurality of light sources to emit light for illuminating the object based on the selected control parameters. - a detector adapted to detect a color and shape of the object to be illuminated; - a database comprising a plurality of pre-stored reflection spectra, color and shapes of objects, a plurality of illumination spectra of said plurality of light sources stored with control parameters for each of said illumination spectra, and results of computations of the color rendering index for each of said illumination spectra; - a control unit in communication with said detector and said plurality of light sources, wherein the control unit is configured to: receive a reflection spectrum of the object to be illuminated by identifying said object through the detected color and shape of the object and by acquiring the reflection spectrum of said object from said database; select, from said database, control parameters for controlling the mixed light emitted by the plurality of light sources such that the mixed light has an illumination spectrum matching the received reflection spectrum of the object and such that a predetermined minimum color rendering index level is achieved; and control said plurality of light sources to emit light for illuminating the object based on the selected control parameters. receive a reflection spectrum of the object to be illuminated by identifying said object through the detected color and shape of the object and by acquiring the reflection spectrum of said object from said database; select, from said database, control parameters for controlling the mixed light emitted by the plurality of light sources such that the mixed light has an illumination spectrum matching the received reflection spectrum of the object and such that a predetermined minimum color rendering index level is achieved; and control said plurality of light sources to emit light for illuminating the object based on the selected control parameters.
