Abstract
Correlated color control (CCT) of a white channel in a color changing lighting fixture is performed by mixing red, green, blue and white light sources. The CCT of the white channel configured or corrected and maintained even while mixing the white channel with the very color channels that are used to configure or correct it. A processing unit uses mathematical models of the light sources to emulate the color temperature of the white components. Using the mathematical models, an RGBW color mix is computed for the white channel alone. The resulting RGBW mix is then combined with levels of red, green and blue as selected by a user.
