Abstract
A color sensor arrangement comprises a color sensor arranged to generate at least a first channel signal being indicative of a color of light incident on the color sensor. A processing unit is connected to the color sensor and arranged to generate a tuple of color signals by processing the at least first channel signal. A memory is connected to the processing unit and a control unit is connected to the processing unit and to the memory. Furthermore, the control unit is arranged to receive calibration data relating the tuple of color signals to a calibrated tuple of color signals and arranged to store said calibration data (M) by means of the memory. An interface is connected to the processing unit and comprises an interface terminal.
