Abstract:
1. A method of generating a control signal for control of a color variation of a color adjustable illumination device, using a user interface comprising a touch sensitive color wheel with a hue that varies in a tangential direction and a saturation that varies in a radial direction, said method comprising the steps of: monitoring the touch sensitive color wheel for user inputs; acquiring a color path input as a curve drawn on the touch sensitive color wheel by a user, wherein said acquired color path comprises a sequence of more than one point, each point of said sequence connected to at least one other point and having an associated hue and saturation, wherein said hue varies from one point to another when the curve is drawn in a tangential direction and said saturation varies from one point to another when the curve is drawn in a radial direction; and generating a control signal adapted to be received by a control unit configured to control the color variation of the color adjustable illumination device, said control signal including information about hue variation and saturation variation of the acquired color path.
