1. A refrigerating appliance, comprising:
a cabinet defining an interior;
a door coupled to the cabinet and configured to moveably open and close the interior;
a lighting device arranged to operatively illuminate the interior based on a predetermined condition, the lighting device comprising a light source and an electrochromic device, the light source arranged to selectively provide a first light to the electrochromic device, the electrochromic device selectively operable to emit a second light within the interior;
at least one energy source coupleable to the lighting device and the electrochromic device;
a controller module communicatively coupled to the at least one energy source, and configured to selectively trigger the at least one energy source to provide at least one of a first voltage having a first magnitude and a second voltage having a second magnitude to the electrochromic device; and
wherein, in response to the at least one of a first voltage and a second voltage, the electrochromic device is configured to modify at least one of an opacity of the electrochromic device, a color of the first light, a color temperature of the first light, and a dispersion of the first light, to define the second light.
