Abstract
A lighting system has first and second light sources operable to generate light having cool and warm white color temperatures, respectively. A color control provides a variable color control signal to adjust a perceived color output of the lighting system. Throughout a range of the color control signal, the controller is operable to smoothly vary the perceived color output of the lighting system between the cool white color and the warm white color. In second and thirds ranges of the color control signal, the perceived color output of the lighting system is the cool or warm white color, respectively.
