Abstract
The invention relates to a method and a system for translating a three value color space signal, preferably given in a CIE scale, to an n primary color space signal, where n is an integer greater than or equal to 4, thus providing color controlling of a white light source comprising an array of colored light emitting diodes with respect to maximum CRI and maximum luminous efficiency.
