1. A light source comprising:
an illuminant array that includes at least three color channels,
wherein each color channel includes one or more illuminants configured to produce a substantially similar color, and
wherein each color channel is separately addressable to produce light of a different color; and
a controller configured to:
identify a color mixing model associated with a correlated color temperature (CCT) among multiple color mixing models based on a characteristic of an image sensor that is responsible for generating an image in conjunction with the at least three color channels being driven simultaneously, and
drive, based on the color mixing model, the at least three color channels to produce white light having the CCT,
wherein the color mixing model specifies how much current is to be provided to each color channel of the at least three color channels.
