Abstract
An apparatus, system, and method are disclosed for identifying and differentiating among multiple groups of devices, comprising at least two LEDs, a controller, and a blending medium. The at least two LEDs emit a wavelength of light that is different from a wavelength of each other LED. The controller drives the at least two LEDs to each emit light at specified intensities in response to a color identifying value. The blending medium combines the light emitted by the at least two LEDs into an identifying color that identifies a group of devices.
