1. A light control system comprising:
- a waveguide defining a passage;
a multicolor light source optically coupled to the waveguide;
a light sensor optically coupled to the waveguide, configured to sense ambient light and operate in conjunction with the multicolor light source to provide a visual effect; and
a controller communicatively coupled to the multicolor light source and the light sensor, whereinthe controller determines a white point of the sensed ambient light and dynamically adjusts an output of the multicolor light source based at least partially on the white point of the sensed ambient light;
the light sensor receives ambient light through the passage; and
the multicolor light source emits the output through the passage.

Abstract
There are provided systems, devices and methods for operating a light source to match a white point of ambient light. In one embodiment, a light control system is provided. The light control system includes a light source and a light sensor. The light sensor is configured to operate in conjunction with the light source to provide a visual effect. A controller is electrically coupled to the light source and the light sensor and configured to determine the intensity and color of light to which the light sensor is exposed and dynamically adjust the output of the light source to match the determined intensity and color of light to which the light sensor is exposed.
