1. A method of operating a lighting device, comprising:
providing power to a light source comprising at least two modes of operation, each mode of operation comprising propagating a beam of light having different spectral characteristics than the other mode, wherein when the two modes are operated, the total spectral output enhances a visual characteristic of a target within an area surrounding the target;
a first mode of the at least two modes comprising a dulling mode;
a second mode of the at least two modes comprising a vivifying mode;
wherein the target comprises a reflective surface having level of reflectivity and wherein the area surrounding the target comprises a reflective surface having a second level of reflectivity; and
wherein the dulling mode comprises propagating a wavelength of light at a first duty cycle and the vivifying mode comprises propagating light at a second duty cycle, the first duty cycle being greater than the second duty cycle.
