Abstract
Disclosed is a control device for controlling a variable-color light source, the variable-color light source comprising a plurality of individually controllable color light sources. The control device comprises a control unit for generating, responsive to an input signal indicative of a color and a brightness, respective activation signals for each of the individually controllable color light sources. The control unit is configured to generate the activation signals from the input signal and from predetermined calibration data indicative of at least one set of color values for each of the individually controllable light sources.
