Patent ID: 8755911

Claim:
An illumination system, comprising: at least one color-rendering lamp assembly capable of generating color-variable light; a controller for generating control signals for the lamp assembly; source color input means for inputting to the controller information defining a source color a memory associated with the controller, the memory containing information defining at least one color harmony rule; wherein the controller is designed to calculate its output control signals such as to define at least one target color as a function of the source color using the harmony rule from the memory, the target color being distinct from the source color and harmonious with the source color; wherein the source color input means comprises a color sensor capable of measuring the color of received light influenced by one or more objects surrounding the color-rendering lamp assembly and generating a measurement signal (Sm) indicating the measured color; wherein the controller is designed to calculate the output control signals independently of the brightness in a two-dimensional brightness-independent color space.
