User interface for controlling intensity and color of a lighting load

Abstract

A load control device may be configured to provide a user interface for controlling the intensity and/or color of one or more lighting loads. The user interface may include separate actuation members for setting the intensity and/or color of the lighting loads. The user interface may include one actuation member configured to operate in an intensity and/or color control mode. The control mode of the actuation member may be set via a button, a lever, a rotary switch, a rotary knob, etc. The user interface may include a touch sensitive element capable of sensing a user's touch and translate the touch into a control signal. Feedback may be provided on the user interface to indicate the type of control being adjusted and/or amount of control being applied to the lighting loads.
