The present invention relates to a lighting control system, comprising a control unit comprising a memory in which control programs are recorded. The control programs are capable of controlling the optical transmission through an active window pane with electro-controllable optical transmission properties and are capable of controlling an electro-controllable lighting device. The system furthermore comprises a coloration sensor for measuring a value representative of a coloration of the light. The control programs are capable of controlling the lighting generated by the lighting device as a function of the value supplied by the coloration sensor.
