Systems and methods for compensating, controlling, mixing and saturating/desaturating colors produced by or emitted from LED artificial light sources through use of multiple channel, LED controllers to control the proportion of constituent colors each to the other, to control the intensity level of the total light output of the mixed, desaturated light during and after color mixing and/or saturation/desaturation by simultaneously increasing and decreasing power to the constituent color LEDs at the same rate, and once a desired color has been produced, changing the intensity/brightness and/or degree of saturation of the produced color without changing the hue of the produced color.
