Artificial light desaturation process
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.

second Kelvin temperature is different from the first Kelvin temperature;
mixing the first white light with the second white light to produce the predetermined Kelvin temperature white; and,
crossfading the base color light of the LED soured light and the predetermined Kelvin temperature white to result in the desaturated base color of the LED sourced light at about the base color light of the LED sourced light first intensity.

providing an LED light source having constituent LED light sources,
the constituent LED light sources including red light emitting LEDs, green light emitting LEDs and blue light emitting LEDs;
producing a first color of light at a first intensity from a first selected one of the constituent LED light sources;
producing a second, different color of light at a second intensity from a second selected one of the constituent LED light sources;
the second intensity lower than the first intensity;
mixing the first color of light with the second color of light by increasing the second intensity and decreasing the first intensity until the resulting color of light is produced at the first intensity to result in the mixed color base light intensity;
choosing a desired desaturation degree for the mixed color base LED sourced RGB color light;
[a] producing a Kelvin-adjustable, phosphor-corrected white light by combining light from first white color emitting phosphor-corrected LEDs with light from second white color emitting phosphor-corrected LEDs, the first LEDs and the second LEDs having different correlated color temperatures; and,
crossfading the mixed color base LED sourced RGB color light with the Kelvin-adjustable, phosphor-corrected white light to produce the mixed color, desaturated LED sourced light at an intensity at about the same intensity as the mixed base color light intensity.
