1. A light fixture comprising:an array of light-emitting diode (LED) light sources corresponding to a color channel of the light fixture;
a driver circuit configured to drive the array of LED light sources; and
a controller including a non-transitory computer readable medium and a processing unit, the controller including computer executable instructions stored in the computer readable medium for controlling operation of the light fixture to:
receive a direct drive signal related to a direct drive signal value for the array of LED light sources,
determine an output of a reference light fixture based on the direct drive signal,
determine a value for a color channel drive signal based on the output of the reference light fixture, the value for the color channel drive signal corresponding to a drive value for the color channel that results in an output of the light fixture that matches the output of the reference light fixture, and
provide a control signal to the driver circuit to cause the driver circuit to apply the color channel drive signal having the value to the array of LED light sources.
