There is disclosed a light color and intensity modulation system having an output to be connected to a color light projector and an input to receive a hue control signal and an intensity control signal including at least one modulation frequency component F. The system comprises a color scaling device, receiving in use the hue signal, the color scaling device producing a plurality of color component signals, the plurality of color component signals being supplied as the output to the color light projector, and an intensity control device, receiving in use the intensity control signal, the intensity control device comprising a low frequency oscillator whose output is an intensity modulation signal for varying an intensity of the plurality of color component signals between a preset minimum and a preset maximum value, the oscillator having a frequency responsive to the at least one modulation frequency component F of the intensity control signal, the plurality of color component signals to control in use the projector. The projected light can have a relaxing visual effect.
