In a light source 100 having N light generators 101-103, a receiver, and an interface circuit 120 each light generator emits light of a different wavelength, the intensity of light generated by the k<th> generator is determined by a signal Ik coupled to that light generator. The receiver receives a color coordinate that includes N color components, Ck, for k=1 to N, wherein N is greater than 1. The interface circuit generates 120 the Ik for k=1 to N from the received color components and a plurality of calibration parameters. The calibration parameters depend on manufacturing variations in the light generators. The calibration parameters have values chosen such that a light signal generated by combining the light emitted from each of the light generators is less dependent on the manufacturing variations in the light generators than a light signal generated when Ik is proportional to Ck for k=1 to N. A method for generating light comprising generator a signal Ik from received colour components and a plurality of calibration parameters is also disclosed.
