Method for providing a light output from a lighting system comprising at least three light sources (102a-c) defining a lighting system color gamut in an x-y color plane, comprising the steps of: receiving a light output target comprising a target color point (210, 219) and a target flux; comparing said target color point with said lighting system color gamut; and if said target color point is within said color gamut: controlling said lighting system to provide a light output according to said target color point; and if said target color point is outside of said color gamut: determining a first approximation color point (212, 220) as the nearest color point within said color gamut based on a minimization of a distance in said x-y color plane between said target color point and said first approximation color point; characterized by determining a highest possible flux achievable by said lighting system at said first approximation color point by determining the maximum duty cycles for the light sources comprised in the lighting system at said first approximation color point (212, 220); if said highest possible flux achievable by the lighting system at said first approximation color point is equal to or larger than said target flux, control said lighting system to provide light defined by said first approximation color point and said target flux; and if said highest possible flux achievable by the lighting system at said first approximation color point is lower than said target flux, determining a second approximation color point (214, 222) at which said lighting system is capable of providing said target flux based on a minimization of a distance in said x-y color plane between said first approximation color point and said second approximation color point; and controlling said lighting system to provide light defined by said second approximation color point and said target flux. receiving a light output target comprising a target color point (210, 219) and a target flux;
