Claim 0:
1. A controller for a lighting system, connectable to a plurality of light sources of different colors and/or different color temperatures, and connectable to a single user control element configured to generate a user selected value from a range of user selectable values, said user selectable values separated in alternately arranged first intervals and second intervals of the user selectable values, wherein the controller is configured to:
receive, from the single user control element, a change of the user selected value, and
as a response to and corresponding to said change of the user selected value, adjust a combined output of said plurality of light sources to produce a change in output color, color temperature and/or a luminous flux of a combined light of the plurality of light sources, such that,
as functions of the user selected value in separated first intervals of the user selectable values, the output color and/or color temperature is kept approximately constant while the luminous flux obtains a local minimum or local maximum in each first interval, and
as functions of the user selected value in at least one second interval of the user selectable values in between the first intervals, the output color at least changes from a first color to a second color and/or the color temperature increases or decreases while the luminous flux is kept approximately constant and,
wherein the controller is configured to enable an independent adjustment of luminous flux and output color and/or color temperature.
