Abstract:
1. An illumination system for generating light with a variable color within a color space, the system comprising: (i) a lamp assembly for generating the light; (ii) a controller for controlling the lamp assembly; (iii) a user input device coupled to the controller for receiving input data comprising a set of coordinates; (iv) a memory defining discrete color points and storing information comprising: wherein the controller is configured to (A) compare the input data with the boundary data to determine location of the color point defined by the set of coordinates in relation to the boundary of the color space and (B) generate color control signals for the lamp assembly, on the basis of at least the input data and a set of values derived from the information stored in the memory, wherein the controller is configured to obtain the set of values by taking: by calculating replacement coordinates of the color point on the boundary of the color space and taking:
